Best ever circum-zenithal arc and my worst camera met on the early evening of July 19, 2017. I drove to Riverside, and on the way, I became interested in the clouds and dispersal of a contrail. It looked like the conditions were right for hole punch clouds. I couldn't take any pictures, because I was driving.
Two hours later I emerged from a building and the sky over head smiled with the brightest and most long lasting arc I'd ever seen. I took numerous pictures with my aim-and-shoot camera and my iPhone. Neither of these devices captures the full color range of bright cloud effects.
