I shot this photo on Sunday afternoon, June 26, 2011, north of Boone, Iowa at 2:25 PM. I was looking to the West when I noticed the rainbow patterns in the sky and took the photo. I did some searching on Google and Wikipedia and I believe it to be something called a Circumhorizon Arc, which forms when sunlight refracts on the ice crystals in cirrus clouds, like we had today at that time. It was beautiful, however a few miles down the road, with that particular angle at the time, I could not see it as clearly as the photo shows.
