Parhelion or Sun Dog

Also called a 'Mock Sun'.

They can appear both sides of the sun at 22 degrees from it and at the same elevation.

They form when ice crystals form in a stable airmass and most of the ice crystals have a similar orientation. This usually occurs at high altitude in cirro-stratus cloud (as here)

The dark clouds are orographic in origin and remained in the same place most of the day.
