See also 22 Degree Halo and Sundogs.

I've seen sundogs a couple of times; 22 degree halos more often.

Sundogs are said by some to be a sign of good luck. But they (or a halo around the sun or moon) indicate the presence of cirrus clouds, which are often a natural indication of an approaching storm.

There is completely different effect which I've only seen from the window of a plane flying above clouds. It is called the brocken specter. It is a shadow which often has a colored halo (glory) around the end opposite the sun. If you're on a mountain with clouds below, with the sun low in the sky, you might see your own shadow with a halo around your head.
