Annular solar eclipse from 15 january 2010 is the longest annular eclipse from all third millenium, about 11min and 8 seconds long and is part of cicle SAROS 141.
The eclipse is seen in eastern hemisphere and here you have an excelent interactive map.
Put your mouse on your location and you will see all details you will nead.
It will be interesting to track SID monitors in the area, to monitor VLF transmissions and the 28 mhz beacons during the phenomena.
Have fun and waiting for your posts.

Strange drops in NAA signal strength

2008-10-09T05:05:00.000-07:00

Earlier I wrote about about how quiet the Sun is lately. As a matter of fact, it hasn't been that peaceful in the last 50 years. Still, it is worth to have a look at the data you collect. Michael Jefferson (running the LOFAR monitor) noticed that at around 02:45 until 03:45 the signal level of the NAA transmitter in Cutler Creek drops quite a lot. It is something I had also noticed and we quickly agreed that this was not caused by out SID monitors but is actually a drop in the signal level of the transmitter. If you go to the SID data browser and single out a couple of the monitors listening to NAA only, you can see that effect. In this picture at this link, you see at the left the drop in signal. Between 10:00 and 22:00 GMT, the signal is completely absent. This is apparently the regular scheduled maintenance period.

Chatting about this, Mike remarked that this is perhaps done to allow painting jobs of the transmitting towers in 1-hours shifted under lower power levels. I personally doubt this, because going up and down the towers leaves hardly any time for the actual painting. Googling around a bit I found that Wikipedia actually mention that painting of the towers is a non-trivial job. They explain that there are actually two arrays of antennas and that one is shut off or '"grounded" when the other half is painted. BTW, the paint itself is apparently somewhat of a health hazard. They also did got a fine because of air pollution.

I was thinking about asking the site itself about the drop in signal, but I cannot find a public contact point. As a matter of fact. according to this EPA report, there are not a lot of public contact points.

Going back to the signal level drops. The Moore observatory in Kentucky is also looking at the NAA and you will find the drops there as well, although not as prominent as we see it. However, this is a pretty good example, while it is also interesting to compare their data on the date with the link above. The drop is hard to see, but the maintenance period is obvious.

So, even when there is not a lot of activity on the sun, there is still a lot to learn from the SID data! :-).

There is some intriguing research about whether large earthquakes are
associated with ionospheric changes. A good overview is the article
by Friedemann Freund, "Predicting Earthquakes," in The Economist, 14
December 2005.

In the laboratory, the crushing of rock crystalline structures generates
electromagnetic fields. The theory is that similar events in the Earth
can affect the ionosphere and thus show up as precursors to large
earthquakes. This research is still controversial and, if there are
effects, they may be too subtle for the SID instruments to pick up.
However, at least one research group claims to have found unusual sunset
signatures associated with the devastating earthquake and tsunami
of December 2004. The paper is: Unusual Sunset Terminator behavior
of VLF signals at 17kHz during the Earthquake episode of Dec., 2004
(http://www.ursi.org/Proceedings/ProcGA05/pdf/EP.18(01596).pdf). They
found the sunset signature was shifted later by 9 minutes, a significant
change. One would think that, for a monitor to pick up these changes,
the epicenter of a large quake would need to fall on or near the line
between the transmitter and receiver. However, these researchers and
the transmitter were in India, a good ways from the epicenter.

Lots of people have by now noticed by now that not a lot is happening at the sun lately. The article "What's wrong at the sun (Nothing)" explains that this is nothing to worry about. These boring non-exiting times apparently do happen all the time! Patience and science are related I'm afraid.

RELEASE: 08-086

NASA SATELLITE DETECTS RECORD GAMMA RAY BURST EXPLOSION HALFWAY ACROSS UNIVERSE

WASHINGTON - A powerful stellar explosion detected March 19 by NASA's
Swift satellite has shattered the record for the most distant object
that could be seen with the naked eye.

The explosion was a gamma ray burst. Most gamma ray bursts occur when
massive stars run out of nuclear fuel. Their cores collapse to form
black holes or neutron stars, releasing an intense burst of
high-energy gamma rays and ejecting particle jets that rip through
space at nearly the speed of light like turbocharged cosmic
blowtorches. When the jets plow into surrounding interstellar clouds,
they heat the gas, often generating bright afterglows. Gamma ray
bursts are the most luminous explosions in the universe since the big
bang.

"This burst was a whopper," said Swift principal investigator Neil
Gehrels of NASA's Goddard Space Flight Center in Greenbelt, Md. "It
blows away every gamma ray burst we've seen so far."

Swift's Burst Alert Telescope picked up the burst at 2:12 a.m. EDT,
March 19, and pinpointed the coordinates in the constellation Bo?tes.
Telescopes in space and on the ground quickly moved to observe the
afterglow. The burst is named GRB 080319B, because it was the second
gamma ray burst detected that day.

Swift's other two instruments, the X-ray Telescope and the
Ultraviolet/Optical Telescope, also observed brilliant afterglows.
Several ground-based telescopes saw the afterglow brighten to visual
magnitudes between 5 and 6 in the logarithmic magnitude scale used by
astronomers. The brighter an object is, the lower its magnitude
number. From a dark location in the countryside, people with normal
vision can see stars slightly fainter than magnitude 6. That means
the afterglow would have been dim, but visible to the naked eye.

Later that evening, the Very Large Telescope in Chile and the
Hobby-Eberly Telescope in Texas measured the burst's redshift at
0.94. A redshift is a measure of the distance to an object. A
redshift of 0.94 translates into a distance of 7.5 billion light
years, meaning the explosion took place 7.5 billion years ago, a time
when the universe was less than half its current age and Earth had
yet to form. This is more than halfway across the visible universe.

"No other known object or type of explosion could be seen by the naked
eye at such an immense distance," said Swift science team member
Stephen Holland of Goddard. "If someone just happened to be looking
at the right place at the right time, they saw the most distant
object ever seen by human eyes without optical aid."

GRB 080319B's optical afterglow was 2.5 million times more luminous
than the most luminous supernova ever recorded, making it the most
intrinsically bright object ever observed by humans in the universe.
The most distant previous object that could have been seen by the
naked eye is the nearby galaxy M33, a relatively short 2.9 million
light-years from Earth.

Analysis of GRB 080319B is just getting underway, so astronomers don't
know why this burst and its afterglow were so bright. One possibility
is the burst was more energetic than others, perhaps because of the
mass, spin, or magnetic field of the progenitor star or its jet. Or
perhaps it concentrated its energy in a narrow jet that was aimed
directly at Earth.

GRB 080319B was one of four bursts that Swift detected, a Swift record
for one day. "Coincidentally, the passing of Arthur C. Clarke seems
to have set the universe ablaze with gamma ray bursts," said Swift
science team member Judith Racusin of Penn State University in
University Park, Pa.

Swift is managed by Goddard. It was built and is being operated in
collaboration with Penn State, the Los Alamos National Laboratory,
and General Dynamics in the U.S.; the University of Leicester and
Mullard Space Sciences Laboratory in the United Kingdom; Brera
Observatory and the Italian Space Agency in Italy; plus partners in
Germany and Japan.

Unix style SID support software available

2007-11-10T11:43:00.001-08:00

As a long time Unix user I didn't like it that the support software for the SID monitor is dependent on the windows operating system. Don't get me wrong, I don't have a problem with the software itself. I'm just not a fan from Microsoft products and I actually didn't have a Windows box running. We brought one up (donated by my employer) and used that only for the SID monitor. I promised to replace it as soon as possible by something else. Since we don't have Excel I made a small script on top of gnuplot to display the data.

Getting tired from the complaints my colleges made about the noise the box made, it was "temporarily" located in the conference room, I finally took the plunge and wrote a little program which collects the data from the monitor. It stores it in a file in a format so it can be uploaded to sid-ftp.stanford.edu as usual.

The current version of all this is not a slick package. However, I think it can be used without too much problems. I want to make it publicly available but I would like to have some feedback before doing so. If you want to give it a test ride, send me mail using the adres "sidmon31 at xs4all.nl". I'll send you a tar ball (ca. 1.3 Meg) with the sources (so some assembly is required :-)). It is developed under FreeBSD 6.2 and compiles on Linux and MacOS X as well.

Note that this is a "Friday afternoon project" so it might take some time before I react. Just pester me again when it takes too much time. Enjoy!

oustanding high school student research

2007-10-18T18:47:00.001-07:00

I'm posting this on behalf of Arum Sharma, a talented Alabama high school student who is participating in the SID program through our NSF/CISM colleagues at Alabama A&M University. During the summer of 2007, following his junior year in high school, Arum participated in AAMU Physics Department’s Astrophysics Summer Research Program. His task for the summer was to analyze SID data from monitors around the world, including the one on top of AAMU's Physics building. By taking raw SID data and generating more visual-friendly graphs using a Linux program, Arum was able to identify the signatures associated with solar flares. He then documented these solar events and measured their intensities using the Geostationary Operational Environmental Satellite (GOES) database. He even researched the effects of local events, such as thunderstorms and daily sunrise, on VLF waves.

Arum recently made a website compiling his research., He's hoping it serves as a useful resource for other students interested in knowing more about SID monitors. Check out:

Great job, Arum!!!

2007-09-01T02:05:00.000-07:00

Hello all from New Zealand.

I am Stuart Weston an M.Phil Student at Auckland University of Technology researching Radio Astronomy VLBI Modelling.

The SID monitor has arrived safe and sound in the Land of the Long White Cloud.

My mate Tim Natush is currently sourcing some wire for the antenna from the electronics lab ( see if they miss a 100m) :-)

The receiver has been connected to the same PC that we use for Radio Jove monitoring. It is an old PIII DELL with Windows XP, bumped the memory to the max 512MB. Couple of disks one for the OS (8GB) and the other for Radio Jove and SID (20GB). Seem's to be handling it no problem with noise down the wire.

So I await my mate Tim to turn up with the wire and we will be online and cooking.

New To the SID Community

2007-06-07T07:16:00.000-07:00

We received our SID monitor in late October 2006. We completed the antenna in January 2007. We had been collecting data haphazardly until a permanent location could be set up. We had a permanent location and were collecting data in April 2007 when this the first week June 2007 the hard drive in our computer failed. We lost all data with the exception of the time period from Apr-20-2007 to May-20-2007 this data was backed up just before this happened. However after this rocky start I have repaired the computer and we have again started to collect data with the SID monitor.

NSF/CISM Space Weather Summer School

2007-04-04T09:47:00.000-07:00

Here is an announcement from Nick Gross, Director of Education for NSF's
Center for Integrated Space Weather Modeling:

"I would like to encourage a few interested teachers to apply for the Space Weather Summer School run by the Center for Integrated Space Weather Modeling (CISM). Stanford is a collaborating institution in CISM and the SID monitors were partially funded by the Center. The Space Weather Summer School is a two week immersion course that is targeted to graduate students who are starting research in space physics. The summer school takes a system approach to space weather exploring the phenomena from the Sun to the Earth, and so it is presented at a conceptual level. The summer school uses innovative pedagogy that includes interactive lectures, question cards for immediate feedback, and computer model visualization labs. During the two weeks, each morning is devoted to a lecture and each afternoon is devoted to the computer labs for students to explore the concepts discussed in the morning. On the last day, students work in groups to follow a space weather storm from the Sun to the Earth.

"Though the summer school is targeted to graduate students, between ¼ and 1/3 or the attendees are other professionals who use space weather in their jobs. Prior attendees have included: teachers, young Air Force officers, radiation biologists working for NASA, and at least one high school student. This is a unique professional development experience and I would encourage you to contact Dr. Gross, CISM co-Director for education (gross@bu.edu ) by the middle of April for more details on how to apply. "

Do SID monitors detect gamma ray bursts?

2007-01-18T17:44:00.000-08:00

Does anybody need a student project? If so,
we have a question: can and do the SID monitors
pick up gamma ray bursts (GRB)?

Several of us think they should be able to detect
these, but nobody has actually gone
to the effort to look. Although the SID
mointors were deliberately designed to filter
out short-lived signals, many GRBs are minutes long.
Or, would our 5 second sampling rate not provide
enough coverage to distinguish a GRB from noise?

If your students can answer these questions, we would
be pleased to highlight their research on our website!

More info on GRBs and pointers to GRB catalogs can be found
in the Wikipedia entry http://en.wikipedia.org/wiki/Gamma_ray_burst

Thanks!

For those of you who are not yet delivering your SID data
to Stanford, it is easy to set up. To transfer your data,
all you need do is set up the "sidsend.bat" script which
was included with your distribution. This script itself
contains information on eanbling it.

Some early distributions did not receive this script, and
some early versions of the sidmon.exe code do not work
with the script. If in doubt, the newest versions of both are

Region 10930 produced a major X3.4/4B proton flare

2006-12-12T22:09:00.000-08:00

Region 10930 changed as the positive polarity spots in the southern part of the main penumbra rotated eastwards. The magnetic delta structure became stronger. Further major flares are possible.

Region 10930 produced a major X3.4/4B proton flare peaking at 02:40 UTC on December 13. 4B is the maximum brightness on the brightness scale and occurs very rarely. Strong type II and IV radio sweeps were recorded and an intense proton storm started at Earth soon after the flare. It is likely that a major very fast Earth directed CME was caused by the flare.

2006-12-05T08:33:00.000-08:00

From spaceweather.com: Earth-orbiting satellites detected a major X9-class solar flare this morning at 1035 UT (5:35 a.m. EST). The source: big, new sunspot 929, which is emerging over the Sun's eastern limb. GOES-13 captured this X-ray image of the blast:

Because of the sunspot's location near the limb, the flare was not Earth-directed. Future eruptions could be, however, because the Sun's spin is turning the spot toward Earth. Sunspot 929 will be visible for the next two weeks as it glides across the solar disk.

Does the SID antena need an impedance adapter

The SID antena, doesn't it need some kind of impedance adapter? Just a thought! The feeder will be a 75 ohm coaxial cable.

correlation between seismic activity & VLF propagation

2006-10-23T14:49:00.000-07:00

There is an article in the current EOS* on "Preseismic
Lithosphere-Atmosphere-Ionosphere Coupling" describing the
relationship between large earthquakes and ionospheric anomalies.
Author is M. Kamogawa. Kamogawa cites several studies that show
significant electron density depression, anomalies in the intensity
and phase of transmitted LVF waves, and variations in the terminator,
sunrise & sunset, times from VLF transmissions up to 11 days before an
M > 6 earthquake He claims these earthquakes were "highly correlated
with VLF anomalies occurring a few days prior". He/She then goes on
to postulate a selection of proposed mechanisms for causal phenomena.
The author concludes that "... atmospheric-ionospheric anomalies before
the earthquakes do exist and their further investigation...remains an
important research endeavor. Determining these connections possibly
will aid with understanding and predicting seismic activity.

At least the changes in sunrise/sunset times and possibly the anomalies in
signal strength should be within capability of the SID monitors to detect.

In need for some answers

2006-10-20T00:15:00.000-07:00

So, here I am again with some problems. As I was saying, I contacted a highschool teacher and we gathered a small group of boys and girls interested in this project. The first problem, building the antena, of course. It is very difficult to find 120 m of wire. So the first question. Can it be made of two or more parts? If yes, how can we make one piece from them? Solder?
Second question. Can we position the antena horizontaly?
Third question. Can it be stored under a roof or must it stay outside in the open?

Thank you

Thanks, Deborah, for inviting me to join the web log. I'm already an experienced blogger so should have no problem.

We are still in process of setting up the Rebel Ridge Observatory here in Sugar Land, TX. Unfortunately, antenna installation have been delayed because of work commitments.

We already have one station running at the George Observatory in Needville, TX.

Will let everyone know when our second is up and running.

I don't know if this was a flare, but our SID monitor shows a feature on
Sept 12 around 21:30 UT that looks like the profile I've been told of:
rapid rise, more gradual fall-off. It also seems to correspond to a
similar-looking feature in the GOES 12 x-ray flux graph.

Anyone else see this in their data?

Comparison of SID Monitor Results for 8/20/06

2006-08-26T14:34:00.000-07:00

In reply to Mike, but in hope that we can share some observations on our observations, I am posting our TLU results with a comparison to the Utah State observations of NML on 8/20/06.

Mike's post of this day should be referenced to the above. The USU data, taken from their website (thank you for sharing), has a flare response almost a factor of 7 larger than ours! Mike's is a couple of times smaller than the TLU data. The noise looks to be roughly the same on these systems (+- 50% at least). Don't really use the TLU data in the above jpeg. It is given for comparison to the USU data. A better scale is used in the earlier post in response to Mike's question.

What did others see? To what extent is the magnitude of the flare response a function of antenna design and to what extent is it a function of antenna locale?

Also in response to Mike's worries, notice that the nighttime measurements, night noise, are greatly different between the two stations. Even the relative location of night to day on the scale is different. I don't even see a strong correlation of ups and downs in the two night noise plots. That might be a neat question to ask for a couple of stations looking at the same xmitter.

Lorne,

Same here....I could not get my image to post in the Comment Section.

Here is my data for 8/20/06. I can see signals in the graph, but the noise is still high. I may need to re-locate the antenna, or build the larger antenna to improve sensitivity. What size antenna do you use for sid monitoring. BTW...I monitor NAA in Maine. My location is Bowling Green KY 65 miles north of Nashville TN.

2006-08-23T18:23:00.000-07:00

With apologies to Mike, KW4MAC, I could not figure out how to get a jpeg file into a comment on
an existing blog item. Our first decent day gave us some sid events, I believe. I checked the bumps against the noaa reports for XRA events on 8/20. If anyone took data that day, I would appreciate a response comparison. I think that my signal is a bit low still. The Stanford Wilcox data is a lot prettier, of course.

We're still setting up our sidmon, so comparisons would help. We're due S of NML, our transmitter in ND.

Hello SID group.

I'm new to SID monitoring. I installed my antenna and sid monitor August 1 and have been recording data daily. I think I see the sunrise/sunset signals and the daytime signal looks like what I've seen with other sid graphs, but my nighttime signal is consistenly low.

Also...I've seen reports of a couple of flares in the last two weeks....Aug. 18 approximatelyh 16:00 UT, for example, but do not see anything on my graph. I'm including the graph I recorded on Aug. 18 to see if this group can help me understand the low nighttime signal and why I might not be seeing flares.

Thanks.

Mike, KW4MAC

Attention all SID monitors!

2006-08-18T13:02:00.000-07:00

Last May a significant meteor fireball fell east of El Paso, Texas. The
event was witnessed by dozens of people and was captured by several
video cameras making up part of the North American All-Sky Camera
Network. These cameras are designed to detect meteors entering the
earth's atmosphere and measured the brightness at greater than magnitude
-13.7 (a full moon is only about -12). A quick time video of the event
can be found at www.geocities.com/desert_lights/latestelpasoevent.htm
. Recent
investigations have suggested that the main mass and terminal explosion
were considerably larger than previously estimated and thus might have
caused ionospheric disturbances. I have also learned that some
eyewitnesses may have heard electrophonic sounds. This is a real long
shot, but those involved in investigating this event would appreciate it
if the members of this group would check their archives for anything
unusual on May 5th around 2150 MDT (0350 UTC, May 5th ). Thanks for
your help.

Please submit by September 9, 2006 to guarantee consideration.

The Solar Cycle 24 Prediction Panel is issuing an invitation for you to submit your prediction for the strength and phase of Solar Cycle 24. There’s even a ‘fun’ component for you non-serious predictors.

As for the previous two solar cycles, the NOAA Space Environment Center is convening a scientific task force of international experts to examine differing forecast scenarios for the amplitude and phase of solar activity during Solar Cycle 24. This task force, with the aid of NASA support, is charged with determining a consensus forecast for the coming solar cycle. The consensus forecast will be published to provide guidance for a myriad of scientific, governmental, and industrial concerns. The panel expects to issue a preliminary prediction by the time of the 2007 Space Weather Week (April, 2007).

For those without a specific prediction model, we’d still like your prediction. The chair of the panel promises to do something fun with the predictions. Fun for a physicist, that is. There might be a prize in it, or at least some notoriety. The chair will just need a long memory.

A SID Antenna Design

2006-08-10T15:02:00.000-07:00

The above two pictures are of the antenna that I put on line last week. Students will return in another week, so I wanted to have something of interest already started. We will worry about data analysis after we resolve some issues with the noise that we seem to have. Our "TLU" SID uses the NML radio station almost due north of us , about 1200 mi along US Highway 281, in central ND. So we see the vast Midwest storm corridor.

Here is the parts list to make our antenna:

TLU Antenna Parts List

1 1/4" Schedule 40 PVC pipe, two 10' stands
1 1/4" PVC pipe cross
1 1/4" PVC pipe Tee, four
1 1/4" endcap, eight

80 lb sack of concrete
large plastic dishpan
2x4" 8' length, three
a few small scraps of 3/8" plywood to shim the support 'V' blocks
assorted wood screws & some spray paint
one long 1/4" lag bolt ( serves as axle during the wire wrapping)
1/4" nylon rope, to be tied in tautline hitch knots
two plastic electrical boxes with covers
some white electrical tape and two crimp connectors

1000' of solid 24 AWG hook-up wire
three PL-259 coax connectors
Times Microwave LMR-400UF low-loss coax cable (a ham radio favorite)
OPEK model LP-350 UHF coax lightning surge protector (a ham radio favorite)

The antenna is quite sturdy and should be able to handle a shielded coax antenna wire (RG174 for small size). The double arm might also be able to accomodate a second pickup antenna in a two-antenna design. I recently discovered a techie VHF reference in "RadioScience Observng, Vol. 1" by J. J. Carr. It's a ham oriented Sams publication that covered lots of the earlier designs I have seen on the web.

If you have interest in this antenna design, I could email or post a whole series of jpg exhibits of the system. Alas, no vacation slides are available. ;)

Many thanks to Shannon & Ray for recently looking at my noise data!

Attention all SID monitors!

2006-08-09T16:45:00.000-07:00

Hello SID monitor groups!

We are making a web page devoted to pictures of your antennae! If you would like your design displayed on our SID site please email us a picture of your set up (multiple angles if you wish).

This will be a great way to show off your pride and joy and also help new builders with your great ideas. No antenna is too small or too simple! We are interested in showcasing all ranges of designs from the most basic to advanced.

Please email your pictures to SID@sun.stanford.edu

Looking forward to seeing everyone's design!

Thank you,

The Janitor Factor

2006-07-14T07:18:00.000-07:00

Stanford SID Monitors
I went in to check on our monitor at the Peabody School in Cambridge, only to find all of the furniture piled in the hall way! I expected the worst and was not disappointed! The monitor and computer was in a pile on a lab bench so the computer table could be moved to clean the floors! I spent an hour tracking down a janitor to find out when the floors would be finished. When I found "Buddy", I was informed the that the summer was not the time for "special electrical space thing experiments". Ugh! After some patient explaining I got out of him that the floor would be ready by next week some time and I could set the computer back up agian.

The good news is that I spoke with a high school student who is working for a summer program that is running in the school and will check up on the monitor regularly. He may also be interested in looking at some of the data and try to make some sense out of it.

I believe someone suggested here that we find a closet to put the computer in over the summer. I thought that was a bit of over kill but it looks like that was the right thing to do. At the very least it should go on a counter that can not be moved. The only problem finding is power and an internet connection.

Hopefully we will be up and running agian with the new SIDMon software next week.

What to do during the summer?

2006-06-20T06:54:00.000-07:00

Hi All,
It is a little late but I thought it would be useful to have a discussion about what different people are doing with their monitor over the summer.

My monitor is actually in an 8th grade classroom of an elementary school here in Cambridge, MA (the Peoples Republic). There is a summer camp run through the school and I am trying to arrange for a responsible and interested councilor to check in on the monitor once a week. A baseline would be for them to just check to make sure it is up and running. If they were interested, they could log the data in a binder and look for any activity. I am meeting with someone this afternoon and we will see what how that goes.

What are other peoples plans for the summer?
Regards,
Nick

Polarity response

2006-06-15T15:49:00.000-07:00

Your power supply should be fine since it is AC and the Monitor needs AC thus the polarity shouldn't matter but to be safe make the center pin should be the load and the outer pin should be neutral!

http://uk.farnell.com/jsp/endecaSearch/partDetail.jsp?SKU=4264976&N=401

The big question is, what is the polarity on the power supply plug on the back of the SID monitor?

I'm still trying to find time to build the antennae in my copius free time :)

April activity discussion

2006-04-21T13:31:00.000-07:00

I would like to see some discussion of the activity this month, since there was some (first in several months.)
In the week of April 3, we saw some classic SID events (see http://www.spacenv.com/~rice/vlf/prv-nmlThru20060409.png), specifically 3 Apr 2130 UT, 5 Apr 1530 UT, and a real beauty on 6 Apr 2030 UT.
There were also some bursts that I'm very curious about: 8 Apr 2000 UT through 9 Apr 0200 UT, 14 Apr 2200-2330 UT, and 17 Apr 1700-2000 UT. There were significant auroral disturbances on 9 and 14 April, but nothing particular on 17 April (poke around in http://www.sec.noaa.gov/ftpmenu/plots/kp.html to see geomagnetic activity levels.) So did anyone else see these bursts, or are they some kind of local interference? Could they be
whistler or chorus emissions? Our operating frequency is rather high for that sort of thing,
but I believe they have been observed up to 40 kHz in some cases. Guess we need an
AWESOME receiver to sort that out.

Nick Gross's comments on quiet time activities are very good. One thing I would add is recording weather events, particularly thunderstorms. Thunderstorms can produce spikes
in the data and may have other effects, even at considerable distances.

Regarding radio propagation, VLF signals are a little tricky. The wavelengths are so long
(tens of kilometers) that they get into a sort of waveguide situation between the earth
and ionosphere. But basically you are correct, the conditions we see in the signal are due to
things going on between the receiver and the transmitter. Rather than simply being reflected
between the transmitter and receiver like shortwave signals, VLF signals can also be soaked up by the lower ionosphere during the day (D region absorption) and may be bounced around in complicated ways around sunrise and sunset. Does Stanford have any VLF ray-tracing (or waveguide mode) software they would care to share with the effort? The stuff I have is for HF and above. Comparing computer predictions with observations would be extremely interesting during quiet conditions.

One activity I would suggest for students interested in the behavior of radio waves at lower frequencies is to keep track of AM broadcast stations with an ordinary AM radio. During the day, you will only hear local stations due to D region absorption. As the sun sets, you will start to hear more distant stations, and after dark the AM band is jam-packed with stations, often talking on top of each other. In the morning you can follow sunrise, as stations in the east fade out before local dawn...then all of the distant stations go away around local sunrise. Here in Utah, I can hear stations from California to Ohio, Mexico to Canada at night. There are all sorts of strange fading and fluttering effects that illustrate various basic physics principles. The
main drawback with listening to AM stations is the content isn't very interesting, especially
at night (unless you are into Art Bell...) Anyway, if you compare the behavior of distant AM
stations to your VLF signal, you will see similarities and differences that are due to the behavior of the ionosphere at the different frequencies.

There is also a rather dramatic change in behavior between winter and summer seasons. I'm
seeing it in the VLF data this month. You can see very definite seasons in our various data sets.
A given day may not be very exciting, but if you collect data for several months, all sorts of
patterns and trends begin to pop out. See if you can figure out the plots on:
http://www.spacenv.com/secblo/BLO/cadi/RX/index.html
Why do the radio station signals have a sort of sine wave variation during the year? Can you
see effects of the Halloween 2003 geomagnetic storm in the 2003 data?

When we collect enough data I'll plot the VLF signal in the same format...should look cool,
though the Tuesday shutdowns are going to mess up the natural variations a bit...

SID Monitors and Solar Min, Why Now?

2006-04-18T14:18:00.000-07:00

I was speaking with Richard Kurtz of South Side High School on Long Island. He has just set up his monitor and has a couple of students beginning some projects using it. He was concerned that it seems like a really boring time to put up a monitor because we appear to be at the very low point in the solar cycle with very little activity on the sun. In our discussion, though we came up with several things that could be done. In fact, solar minimum is the perfect time to start large scale testing of a new instrument, and what amounts to a new instrument network that will very soon become a global network. During solar minimum, with very few interesting events, we can get some base line data for how each instrument is supposed to behave.

<>There are several interesting issues that we need to explore regarding our monitors. One of the first things you should try to figure out is when does the particular station that you are looking at go down for maintenance. Each of the VLF stations, which are run by the government and used mainly for military traffic, goes off the air once a week or so for maintenance. It happens pretty regularly. If you take plots for say three weeks worth of data and past them up, you should see the maintenance period three times. Try to figure out which day of the week it is and post that on the blog so we can compare notes. (It looks like NML goes down on Tuesday Mornings.)

A second thing you should be able to do is identify sunrise and sunset. There is a characteristic drop in the signal strength at sunrise and a rise in the signal strength at sun set. Using the weather service or other reference (almanac?), you should be able to find your local sunrise/sunset times and see how it compares to your time. Notice that the student will have to convert everything to UT, which is another classroom activity you can do, especially in the lower grade levels.

<>Related to this is a more interesting issue. The effect measured by each monitor tells you about the state of the ionosphere at the point where the radio waves reflected. This means that a monitor in Boston tuned to a receiver in North Dakota is probing the ionosphere in the Midwest somewhere, assuming there is only one reflection. In that case, the sunrise effect will occur at sunrise at that point. Similarly, a monitor in California tuned to the same station is probing the ionosphere over Nevada, I think. This assumes that there is only one reflection. The question is can we verify that. I have a couple of thoughts on this matter but perhaps your students can come up with some ways to do this. Once you have an idea as to where the reflection is coming from, it should be simple geometry to get the reflection angle. This may be important to understand how the radio waves are interacting with the ionosphere.

Finally, you can begin to look at details of the data itself. There are some interesting daily features, and a good project would be to map some of these. For example, there is a hump right after sun rise. Does this change from day to day and season to season? Does it very by location? Similarly, different locations see a different shape during the day. Is this due to the location or due to the calibration of this instrument? I am sure there are other questions out there that need answering.

A research group at NCAR recently reported a predication that the next solar cycle was going to be 30% to 50% larger then was previously predicted. A news report on this is at http://www.csmonitor.com/2006/0309/p02s02-stss.html (If you can’t get this link, contact me and I will send you the report that I down loaded.). It is thought that this next cycle will begin in late 2007. By putting up your monitor now, working out these kinks and exploring the quiet period to know how each location responds. We will be ready when the real fun begins (just before the lights go out completely).

2006-04-17T12:11:00.000-07:00

Hi There to the SID Monitor Community. Our Monitor in Cambridge MA (the Peoples Republic of Cambridge) has been up in an 8th grade classroom for a month now and we should be automatically uploading our data automatically soon.

I wrote up a "press release" for the school news letter and I think it will be going out to the local papers. I am including it here. It was reviewed by someone with newspaper editing experience and Deborah Scherrer has looked at it. Feel free to copy it and adjust it to your local needs.

======================= Text Below this line=========

Peabody School Part of International
Space Environment Monitoring System

Students and parents entering the Cambridge’s Peabody Elementary School on Rindge Ave. from the rear may have notices an addition to the roof of the building. The addition is a Very Low Frequency (VLF) radio antenna that is connected to a specialized receiver located in Mr. Edward Rice’s 8^th grade science classroom. This, along with the internet connected computer, make up a Sudden Ionosphere Disturbance (SID) Monitor. This device and others like it distributed around the country, and even around the world, are part of a science experiment to detect changes in the Earth’s upper atmosphere caused by activity on the sun.

The receivers were developed at Stanford University in Palo Alto, California and are partly supported by National Science Foundation (NSF) funds through the Center for Integrated Space Weather Modeling (CISM) in the Astronomy Department at Boston University. A Peabody parent, Nicholas Gross, is the co-Director for Education in CISM and provided the initial contact between the research program and the Peabody School. The radio receiver is provided by the project and the antenna was built here at Peabody.

The receiver is pre-tuned to the frequency of a VLF radio station run by the government in North Dakota. Radio waves at these frequencies reflect off the upper layer of the atmosphere back to Earth. In this way they can travel very long distances, even around the world. The strength of the reflection can change depending on the state of this topmost layer of the atmosphere, called the ionosphere. The ionosphere can be changed by activity on the Sun, such as solar flares, which will increase the density of charged particles in the upper atmosphere. This will change the strength of the radio signals received by the antenna on the Peabody School Roof. The strength of the signal is measured by the receiver and collected on a computer every 5 seconds. The data is regularly uploaded to the Solar Center at Stanford and placed in their database. It can then be compared with data from other receivers to see local, regional and even worldwide differences.

Students and teachers at Peabody can use the monitor and the Solar Center database to enhance their regular curriculum on the Sun and its effects on the Earth. It can also be used as the basis for impressive Science Fair Projects that are out of the ordinary. Mr. Rice noted that often students do not feel connected to the star in our backyard, only 93 million miles away. The monitor provides a tangible connection that the students have never before experienced before. Mr. Jay Mahoney, the 7^th grade technology teacher, will also take advantage of the monitor to illustrate the use technology in exploring the world around us.

Though the Sun is currently quiet, it is expected to become more active starting next year as it goes through its 11-year solar cycle. Predictions for this next cycle suggest that the activity will be very high, providing many opportunities to ask interesting questions that can be answered by the data. The effects of this increased activity will also be apparent by increasing problems with radio communications, satellite malfunctions, power fluctuations, and increased danger of radiation exposure to astronauts.

The Peabody School is currently one of five schools in the database and the first school outside of California. Approximately 35 monitors have been shipped to various schools around the country and the program plans to place 100 of the monitors. The United Nations has designated next year as the International Heliophysical Year (IHY) (The heliosphere is the region that is influenced by the Suns magnetic field and the solar wind, well beyond the orbit of the planets.) The plan is to place a monitor in every country in the United Nations. In this way, students at Peabody will not only be connected to the Sun, but will be connected to other students around the world who are also studying the sun. In this way, the international connection of science can be experienced by students at the middle and high school level.

About plugging in speakers with SID hooked up

2006-03-07T14:48:00.000-08:00

According to our Chief Engineer, Ray Mitchell, plugging the speakers in and out can
cause data collection problems. However, if you want to have the speakers connected all the time,
then always have them connected -- even when you aren't listening to them. Ray had
noticed that the data collected was lower when the audio speakers were plugged in
and higher when unplugged. And the volume level also somewhat affected the readings.
He does not understand why this is happening. They have a buffer and a decoupling capacitor
between the SIDMON and the external speakers, and haven't been able to figure out why
this strange behavior. However, it is a known issue and one that they will be working on.

2006-03-07T11:42:00.000-08:00

According to a new solar cycle model, based on the MDI data from here
at Stanford, the next solar cycle may be quite a bit larger than the last.
This should make our SID monitoring quite interesting! Details on
the research can be found at:

2006-01-24T14:35:00.000-08:00

This is a (probably-temporary) blog set up for people hosting a Stanford SID space weather monitor. Welcome! We hope to be able to exchange information about setup problems, improvements to the hardware, software, or documents, and mutally answer questions amongst ourselves.
