1~21~12~ Space Weather Update~ Waiting for the CME to Arrive~
WHILE WAITING FOR THE CME... An incoming CME of Jan. 19th (see below) has not yet arrived. Nevertheless, auroras are already dancing around the Arctic Circle. This was the scene last night over Chatanika, Alaska:
"My fellow Fairbanks aurora chaser, Roger Marty, is shown here shooting a corona as the display began to peak," says photographer Ronn Murray. "Perhaps we got a sneak peak of what's to come with tomorrow's expected CME from sunspot AR1401."
Indeed, it could be a preview. NOAA forecasters are estimating as much as a 25% chance of polar geomagnetic storms when the CME arrives during the next ~36 hours. High latitude sky watchers should remain alert for auroras. Aurora alerts: text, voice.
