February 27 2014 CME IMPACT TRIGGERS GEOMAGNETIC STORM: A moderate G2-class geomagnetic storm is in progress

CME IMPACT TRIGGERS GEOMAGNETIC STORM: A moderate G2-class geomagnetic storm is in progress following the glancing impact of a CME on Feb. 27th at 1645 UT. Sky watchers in Europe are reporting bright auroras. Ruslans Merzlakovs sends this picture from Nykøbing Mors, Denmark:

"A very bright aurora splashed in the afternoon sky at 9 P.M. Danish time," says Merzlakovs. "This picture is a 30 second exposure at ISO 1600."

NOAA forecasters expect CME effects to last for as much as 24 hours. As night falls across North America, auroras could appear in northern-tier US states from Maine to Washington as well as Canada. Local midnight is usually the best time to look.
