Make that an X9 flare!

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.

Region 10930 is a complex region capable of producing further major flares. There is a magnetic delta structure in the northwestern part where negative polarity is nearly embedded within a strong positive polarity area. Flares: C2.2 at 02:03, C3.9 at 05:09, C4.2 at 06:26, M1.8 at 08:03, C1.5 at 09:11, major X9.0/2N at 10:35 (associated with a strong type II and a moderate type IV radio sweep), C1.7 at 16:15, C1.2 at 17:22, C5.8 at 20:07, C3.7 at 20:54 and C1.5 at 23:55 UTC. The X9 flare was associated with a minor increase in proton levels. An X9 flare at this stage of a solar cycle is very unusual and seems to have caused problems for some instruments on GOES-13. This is an image from GOES-13 a few minutes after the flare peak (and shortly before imaging problems were noticed)

X9 Flare

The SID monitor in Amsterdam noticed this one clearly.

I cannot figure out how to post a graph here else I would have done that.
