  Observing tips: Look west 30 to 60 minutes after sunset when the Sun has dipped 6o to 16o below the horizon. If you see luminous blue-white tendrils spreading across the sky, you've probably spotted a noctilucent cloud. Although noctilucent clouds appear most often at high latitudes such as Scandinavia and Canada, they have been sighted in recent years as far south as Colorado, Utah and Virginia. NLCs are seasonal, appearing most often in late spring and summer. In the northern hemisphere, the best time to look would be between mid-May and the end of August.

The mellow and slow moving NLCs were present in the northwest after sunset, as opposed to northeast before sun rise most of the other times I've seen NLCs. Will this be the last of the season..?

This panorama was composed from 10 vertical images shot with a Nikon D200 and a 28mm lens. At around 3 AM the display reached closer to the southern horizon than the zenith.

Another fantastic display of NLC!!! I was up all night watching these wonderful "clouds" and they changed in structure and brightness all night.....a moment to remember!
