~Space Weather Update~CME IMPACT, GEOMAGNETIC STORM [1]
CME IMPACT, GEOMAGNETIC STORM: A minor geomagnetic storm was already in progress on Feb. 19th when a CME struck Earth's magnetic field at approximately 0200 UT. The impact revved-up the storm and sent Northern Lights spilling across the Canadian border into the United States. Douglas Kiesling sends this picture from Sauk Rapids, Minnesota:

"The auroras were so bright, I could actually see a snowy owl on power pole back lit by the green glow," says Kiesling. "The owl itself was illuminated by bright moonlight."
High-latitude sky watchers, if it's dark where you live, look for auroras. Geomagnetic activity is still underway [3] as Earth's magnetic field reverberates from the CME impact. Aurora alerts: text [4], voice [5]
