Rainbow

This photo was taken about an hour after the sunrise photo below. The photo is not particularly special, and the colors had begun to fade by the time I snapped it. I'm posting this photo because I think it's unusual. This is not a normal rainbow. It's not in the shape of a rainbow and it did not appear under the conditions when you would usually find a rainbow. I'm not really sure what this is, but I'm sure the prism must be related to the sunrise and the atmospheric conditions at the time. Another bright spot in my day at work.
