CME Impact Sparks Geomagnetic Storm

Source - Space Weather News for Oct. 1, 2012: http://spaceweather.com

CME IMPACT: A coronal mass ejection (CME) hit Earth's magnetic field on Sept. 30th.  At first, the impact was weak and produced little effect, but now (the early hours of Oct. 1st) moderately-strong geomagnetic storms are brewing in the CME's wake.  High-latitude sky watchers should be alert for auroras, especially during the hours around local midnight.  Glare from the Harvest Moon will reduce visibility.
