Excellent NLC Display

On Thursday night we had an excellent display of Noctilucent Clouds visible from across Northern Ireland. This was a fairly low display only 10-12 degrees above the horizon but was notable for its brightness - indeed it was probably the brightest display I've ever seen. It covered some 60 degrees of the horizon and appeared quite suddenly out of the twilight - it doesn't get properly dark here from the middle of May until the end of July.

Here's the photos...
