Nice shots tep. I hope that I get to see this one day. You are very lucky.

They are called nacreous clouds.

The waves are due to high altitude winds.

It wouldn't surprise me if those types of clouds got mistaken for UFOs.


And great pictures by the way!
I would love to see nacreous clouds in real life.

Very nice pics, they would make nice wallpapers
