Yesterday, Sept. 6th at 0150 UT, sunspot 1283 produced an M5.3-class solar flare followed by a X2.1-class event at 2220 UT. A movie from NASA’s Solar Dynamics Observatory shows the flash of extreme UV radiation. Because of the sunspot’s central location on the solar disk, the eruption was Earth-directed and a CME might be heading our way.
The two eruptions hurled clouds of plasma (CMEs) in our general direction. A preliminary analysis of SOHO and STEREO imagery suggests that the CMEs could sail substantially north of Earth, delivering a glancing blow to Earth’s magnetic field as they pass. ETA: Sept. 8-10.
