The Green Flash

The elusive green sunset flash appeared this evening over Lake Erie while I watched from my back yard.  Unfortunately, I didn't catch it with the camera but it was the first time I had ever seen it.  The top rim of the sun flashed into a bright emerald green color for a brief second or two.  If you've never heard of the green flash before, here is a good article that explains the phenomenon:  http://www.universetoday.com/47607/green-flash-sunset/

The buildings visible on the horizon in this photo are in Nanticoke, Ontario.
