WAITING FOR GEOMAGNETIC STORMS: A CME struck Earth's magnetic field during the late hours of Sept. 6th. So far the impact has done little to stoke strong geomagnetic activity. Another CME is on the way, however, and it is more potent, having been accelerated in our direction by yesterday's powerful X9-class solar flare. NOAA forecasters say strong G3-class geomagnetic storms are possible on Sept. 8th when the inbound CME arrives. Free: Aurora Alerts
MAJOR X-CLASS SOLAR FLARE (UPDATED): On Sept. 6th at 1202 UT, sunspot AR2673 unleashed a major X9.3-class solar flare--the strongest solar flare in more than a decade. X-rays and UV radiation from the blast ionized the top of Earth's atmosphere, causing a strong shortwave radio blackout over Europe, Africa and the Atlantic Ocean: blackout map
