Lenticular clouds, technically known as altocumulus standing lenticularis, are stationary lens-shaped clouds that form at high altitudes, normally aligned at right-angles to the wind direction.

I want to go to there. This particular formation is an example of Undulatus asperatus--meaning "agitated waves"--which was proposed as a separate cloud classification in 2009 by... wait for it... the founder of the Cloud Appreciation Society. (I'm serious.)

Sundog Light Phenomenon, Manitoba, Canada, 2005 Photograph by Norbert Rosing A solar phenomenon known as a sundog arcs over the tundra in Churchill, Manitoba, Canada. Sundogs are fairly common occurrences in the Arctic and Antarctic. They form when the sun is near the horizon and ice crystals high in the sky line up in a way that bends the solar rays like a prism.
