Unusual CloudsThese clouds are similar to those shown in picture #783. They were photographed in January 2000 and were visible for about an hour at sunset. They occur in very cold conditions at an altitude of 9 to 16 miles. They are called "nacreous" clouds, after the old term "nacre" which means "mother of pearl".

It's very beautiful, like a silk screenprint.
