Leaving work I saw iridescent clouds, which began to firm into KH waves. Before I left my biz park I pulled over and took 3-4 pics. This was the best one. Within 5 minutes I was on the highway heading South and they had dissipated only to reform again with only 4 waves over the length of a dozen or more kilometers long cloud These also dissipated within a few minutes. Keep looking up! But always drive safely.
