Clouds

I've only ever once seen noctilucent clouds, when I was in northern Finland. They apparently form at about 85km height, well after sunset, and are water vapour on dust particles from space. Amazing video.

Re: Clouds

That's strange because I always thought the sun never set in Finland. When I went over there a few years ago, it dipped down at midnight for about 5 minutes then went back up. Cool_smiley
Good video though.

Re: Clouds

@Gandalf  Don't forget that in winter it's the exact opposite and the sun only shows itself for a short time, so there are vastly varying hours of light/darkness according to the time of year.  Wink
