*GEOMAGNETIC STORM WARNING:* A CME has just hit Earth's magnetic field 
(Sept. 7th at ~2300 UT). This is the debris from Wednesday's 
decade-class X9 solar flare. It arrived earlier than expected, 
confirming that the solar storm cloud is both fast and potent. The CME 
appears to contain strong south-pointing magnetic fields that typically 
do a good job of igniting geomagnetic storms. High-latitude sky watchers 
should be alert for auroras in bright moonlight. Visit Spaceweather.com
