Green Sunlight Aurora

A coronal mass ejection hit Earth's magnetic field on Oct. 8, 2012 sparking a dramatic display of Arctic lights that is only slowly subsiding three days later. The Aurora appears to be casting rays of green sunlight through the clouds. Hugo Løhre photographed the auroras over Lekangsund, Norway, on Oct. 10, 2012.
