On Oct. 24, 2011, the Northern Lights glowed over North Alabama, visible even though the skies were bright from city lights.

 

Aurora Borealis, or Northern Lights, are unusual so far south -- the colorful, 20-minute display was a rare sighting caused by a recent solar storm. This video was captured by the color allsky camera at the Automated Lunar and Meteor Observatory, or ALaMO, at the Marshall Center in Huntsville, Ala.
