Noctilucent Clouds Over Ottawa

Noctilucent Clouds Over Ottawa

Its not often you get a phone call at 4am saying “Look Up”, but today I did and it was for quite a sight! Apparently some ultra high level clouds (+75km up) were hovering above Ottawa and visible, a rarity for sure. This type of cloud is illuminated by sunlight from below the horizon so only visible just after sunset or just before sunrise.

More info can be found on Wikipedia about the phenomena, I also made a short video panning the cloud structure.
