My photographs of the aurora display on 5/15/2005 came back. Pictures were taken at between 07:00 and 09:00 UTC, 5/15/2005 ( 01:00-03:00 AM MDT, 5/15/2005 ) looking from azimuth 0°N to 70°E from N 40.8 Lat. Times are by UTC hour segment unless otherwise noted. The field-of-view in each image is approx. 30° by 15°.

Best shots are:
