Double Sundog

October 11, 2012

I witnessed a double sundog this week. It was very exciting for me because I actually predicted these by the appearance of the clouds and when I drove up to the mesa, sure enough, there they were, bright and surprisingly clear.

Sundogs always appear level to the sun and to the left or right of the sun. They generally appear 22 degrees distant from the sun and the same distance above the horizon. I see an amazing number of sundogs here in New Mexico, but this week was the first time I saw sundogs on both sides of the sun at the same time. As you may recall, Sundogs have a reddish-orange edge facing the sun and bluish-white tails that shoot away from the sun. The colors are generally fuzzy, particularly the orange/red section, but this time one of the sundogs was crisp and bright. The double sundog appeared on the border of Rio Rancho and Albuquerque, New Mexico, viewed from the mesa west of town, on October 8, 2012.
