Noctilucent

Having seen them periodically over at the Astronomy Picture of the Day, and more recently on GS's photostream, it was nice to finally see some noctilucent clouds for myself ...


These were only visible for a short period, and more-or-less disappeared while I was trying to photograph them (stupidly sans tripod). Anyway, now that I've seen them over the city once, I'm on the lookout for a repeat performance.
