By coincidence, just after finding the unusual photo of Jack and Jill windmill, I came across another unusual photo of
a windmill.
Aurora Fantastic! contains
photos of Balleycopeland windmill, County Down, Northern Ireland, taken during the evening of 21st January 2005, when the
sky was lit up by the Aurora Arc. Most spectacular. (Taken by a member of the East Antrim Astronomical Society).
