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.
