Unseen colourful cloud [Not photoshoped].
When i was in Norway i saw this cloud. Never seen such clouds in my life.
This is not aurora, it was single cloud in the sky. I googled this phenomenon.
And it is called Iridescent clouds. This happens when the sun reflects very
small droplets or ice crystals at some angle. At least it was not a chemical cloud.
That's what happens when an airplain run over a rainbow ;D
Haha, funny :D but in physical conditions it is kinda the same occurrence.
