  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.

After a thunderstorm at sunset this evening I was suprised by a beautiful display of mammatus-clouds. As a bonus one hour later I got my first Noctilucent Cloud-pictures of this season. Probably the sky was clearly washed after the heavy rain to display this fine NLC show.

Photo details: Nikon D70, set at noise reduction and 200 iso. Exposure time around 5 seconds with several Nikon lenses from 10,5 mm fish-eye to 200 mm tele.

Bonus for staying at work late: noctilucent clouds, after a thunderstorm Cb leaving north-west (to the right on the photo and film), with bright Venus over the horizon. It was time enough to catch fading NLCs on a movie.

Photo details: Nikon Coolpix 8400, zoom at 24 mm equivalent, time lapse sequence every 30 seconds from 21:56 to 22:21 local daylight saving time.

What I've learned about NLC is that they can look almost like anything, the structure and brightness is different from time to time. Tonight I only saw this NLC filament in the sky; it showed up and dissapeared in a hour.

Photo details: Canon DLSR, 75mm lens

After a turbulent day with violent thunderstorms and showers, the skies cleared and from past experience I knew that there might be a chance there would be NLC visible that night. And surely, at around 23.00h local time, during twilight, bright, electric bleu tendrils were visible very hight in the sky, at about 50o altitude. That is very unusual. I was able to follow the NLC's until they were at 20o some twenty minutes later and were obscured by "regular" clouds. Very beautiful!

Photo details: Olympus E500, ISO 200, Zuiko Digital lens @14mm (:f28mm in 35mm format)5 second exposures.
