Aurora Alert



"A coronal mass ejection (CME) hurled into space by a solar explosion on April 6th is heading in the general direction of Earth. Sky watchers should be alert for auroras when it arrives, probably during the early hours of April 8th UT (for North Americans, that means during the night of April 7th).



Earth is already skirting through a solar wind stream flowing from a coronal hole on the sun. Because of this, geomagnetic storms and auroras are likely, off and on, for the next few days. The best displays will be at high latitudes--e.g., Canada and Alaska. When the incoming CME arrives, auroras could descend to lower latitudes, too..."
