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
While enjoying a few days on the road during this past week, I got these shots of some nice sundogs over the Long Island Sound:

Sundogs are about 22 degrees (two fists or one outspread hand) on either side of the sun.
You can read about how sundogs form at Les Cowley's atmospheric optics page:
