Jeffrey R Hapeman took this picture of an aurora over Lac du Flambeau, WI on May 29, 2005. He accounts his experience, �Very bright but diffuse aurora from the CME last night. Highest intensity was between 12:30 and 1:30am Central Daylight time. There were rays and beams, and the show was quite impressive. I used a Canon 1Ds Mark II at ISO 1600 to capture this 30s exposure at f/2. The pinks reds and blues were not visible to the naked eye.�
