STRONG SOLAR ACTIVITY: Sunspot 1283 is crackling with solar flares. Yesterday, Sept. 6th, the active region produced an M5.3-class eruption at 0150 UT followed by a X2.1-class event at 2220 UT. NASA's Solar Dynamics Observatory recorded this extreme UV flash from the X-flare.
The flares produced waves of ionization in Earth's upper atmosphere, briefly altering the propagation of low-frequency radio signals around our planet. Moreover, 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.http://spaceweather.com/
