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.
