Nacreous Cloud


Laurent Alquier, a connoisseur of unusual atmospheric phenomena, sent me this photo from his collection, with the following comment:

This is a case of Nacreous Cloud, horizontal rainbow diffused throughout a cloud layer. Apparently, these can be seen in northern countries closer to the pole.

REally Stunning! Have you ever seen a Sun Dog? If your photographer friend has one it would be wonderful to see.
