Nature Rainbow in the cloud

Rainbow in the cloud · 05:51 AM

I'm not posting this because it's a great photo. I'm posting because I want to know if anyone has seen this before. It's a circular rainbow around the sun at sunset. I think it's caused by ice crystals high in the atmosphere. I've seen vertical band of rainbow like this and I've seen this effect around the moon, but I've never seen it around the sun before. I've increased the saturation to highlight the rainbow.

Not necessarily a sun dog.

Go here Atmospheric Optics for lots of atmospheric phenomena explanations.
