Here's another photo of the circumzenithal arc above the Sun Dog I saw on Tuesday. However this time, another faint rainbow halo is visible. This is a Supralateral arc. https://en.wikipedia.org/wiki/Supralateral_arc This Sun Dog just kept doing strange stuff in the sky, and it's all due to these ice crystals in the atmosphere refracting sunlight in funny ways. Thank you ice crystals for giving us this really weird show in the sky.
