On our approach to the Denver airport 2 weeks ago, Mr. Patrick and I were treated to an interesting optical effect called a "glory", and we've posted a video of it on Youtube.
You can read about how the glory forms here

Sundogs are about 22 degrees (two fists or one outspread hand) on either side of the sun.
