High altitude ice crystals.

Thank you for posting this! It's a beautful phenomenon, caused by (as Steve wrote) high altitude ice crystals. On a recent flight from Sacramento to Burbank (California), at 36,000 feet I was able to see almost a full-circle halo (or "sun dog") around the sun caued by this effect. There were even a few times where the secondary rings appeared.
