More solar outbursts on Monday have created the conditions for the Northern Lights to again be visible (maybe!) across the Cape and Islands tonight.
Earlier this week, on Monday night, the Northern Lights were visible from our shores.
Dr. Michael West, astronomer with the Maria Mitchell Observatory on Nantucket, explains what causes the Northern Lights, and has some tips for the getting the best views, in his conversation with Steve Junker on All Things Considered.
That discussion is posted above - give it a listen.
