Circumzenithal arc


Monday, January 6, 2014, extremely cold in the Lafayette area.  At about 11 am it was about -15 degrees F.  The sun was surrounded by a bright white halo, with two colorful sundogs on either side.  Brightest sundogs I have ever seen  I looked up and nearly overhead there was this circumzenithal arc.  First time I ever saw one of these. It brightened when it was crossed by the fast moving low clouds.
