Nacreous Clouds

Nacreous clouds are located in the stratosphere between 9 and 16 miles high. Their "mother of pearl" colors come from sunlight striking tiny ice crystals inside the clouds. Very low temperatures near -85o C are required to form the crystals, which is why nacreous clouds are seen mainly during winter over places like Alaska, Iceland and Scandinavia. This photo was taken in Trondheim, Norway (12/17/08), by Ivar Marthinusen. For more information click on http://www.spaceweather.com/
