Where the data comes from
Two rules hold this site up. A value is never shown without the time it was read at. And a feed that fails keeps its last value with its real age, or shows nothing — never a zero, never a stale number presented as current.

Cameras we link to rather than show
FMI's all-sky aurora cameras. They are not openly licensed, so every aurora page links to FMI's all-sky camera images instead of showing the image.
Ski resort, hotel and port cameras. Levi, Ylläs, the Port of Helsinki and the Port of Turku run their own cameras under their own terms, and none of those terms allow a third party to embed the picture. They are links in the camera gallery, never images.
