Paraphrasing Wikipedia, a sundog is formed in very cold weather by ice crystals called diamond dust drifting in the air at low levels. As the crystals sink through the air, they become vertically aligned. Sundogs are red-colored at the side nearest the sun.
I've only seen a few sundogs, and they thrill me every time. I never expected to see one in May. Hmm, so there's an upside to doing chores at 14 degrees, even in May.
Believe it or not, the day warmed up quickly, and it was actually a pretty darn nice day.
