All Night Sky
Public all-sky cameras that record each night as a timelapse, a star trail composite, and a keogram.
All Night Sky shares cameras that spend every clear night staring straight up. Aurora, meteors, the moon and planets, and — this being Alberta — a great deal of cloud.
What a night looks like
Each camera site has its own page with the current weather conditions and a table of evenings. For every night there are three views:
- Timelapse — the whole night compressed into a short video
- Star trails — a stacked composite showing the sky’s rotation
- Keogram — a single strip image summarizing the night, so you can spot the interesting minutes without scrubbing through the timelapse
The keogram is the one that earns its keep. Finding a brief aurora burst in a whole night of video is tedious; finding the green smear in a keogram takes a glance.
Current conditions
Alongside the imagery, each site reports temperature, humidity, and wind speed, with a short history. Cloud cover explains most of what a night’s video does or does not contain, so the weather record is worth as much as the footage on the nights when nothing is visible.
The pages update live rather than waiting for a reload, and times are shown in the camera’s own timezone.
Cameras
There is currently one public camera, in Sherwood Park, Alberta. The site is built to hold more than one, and the administrator’s address on the about page is there for anyone who wants to contribute a feed.
