It was a beautiful summer evening, with stars wheeling overhead in a moonlit sky and the only clouds far away and interesting.
This was one of those nights we get once or twice a summer when the much-anticipated noctilucent clouds – the clouds of summer – put on a perfect show. In my previous post I featured an image from early in the night, last night, June 26, 2013.
These are images and time-lapse movies from later in the night. The composite image above shows stars trailing over 90 minutes with the brilliant noctilucent clouds on the horizon, and fringed by a rosy glow of red twilight where the southern edge of the cloud display, which sits over the Northwest Territories, is being lit by a setting Sun with red sunlight filtering through our atmosphere as it passes over the North Pole.
This telephoto lens shot above captures a close-up of the rosy-fringed noctilucent clouds, behind a lightning-lit thunderstorm rolling through storm alley in central Alberta. The storms can stay there! We’ve had enough of them for a while!
My time-lapse sequence extends over about 90 minutes and opens with a wide-angle view of the display as it appeared low on the horizon. What follows are two closeup views that really show the intricate wave-like motion of these high-altitude mesospheric clouds, and their changing lighting and colours.
These are beautiful clouds drifting on the edge of space but it takes time-lapse to reveal their fluid-like motion.
