What are sun pillars?

Published On: Jul 27 2011 01:16:05 PM EDT

A sun pillar is a vertical shaft of light extending upward or downward from the sun.

Typically seen during sunrise or sunset.

Sun pillars form when sunlight reflects off the surfaces of falling ice crystals associated with thin, high-level clouds like cirrostratus clouds.
