CME Impact, Geomagnetic Storm
Arriving a little earlier than expected, a CME hit Earth's magnetic field on Oct. 2nd at approximately 0200 UT. The impact sparked a G2-class geomagnetic storm with auroras across Canada and several northern-tier US states. Alan Dyer sends this picture from Gleichen, Alberta:
After the CME hit "I made a point of checking the sky and, sure enough, a fairly bright aurora was present all across the northern horizon," says Dyer. "The camera picked up red bands as broad and intense as I've seen."
The show's not over. Solar wind in the wake of the CME is blowing strong while magnetic conditions favor more storming. High-latitude sky watchers should remain alert for auroras.
