Subsiding Geomagnetic Storm

A geomagnetic storm that sparked auroras around the Arctic Circle and sent Northern Lights spilling over the Canadian border into the United States on April 12th is subsiding. At the height of the display, Shawn Malone took this picture from the shores of Lake Superior near Marquette, Michigan.

"I coaxed myself out of bed around 4am and was rewarded by a lightshow!" says Malone. "The auroras had no problem shining through the light pollution. I think the sun IS waking up. I watched the Northern Lights until the sunlight wiped them out."

NOAA forecasters estimate a 25% chance of more geomagnetic activity during the next 24 hours. -- Space Weather
