Late afternoon looking out the kitchen window I spotted this faint sundog in the cloudy sky, it stayed there for about half an hour.
This is only the second sundog I have been lucky enough to capture, as most times when I have seen one I haven't had a camera with me.

Another name for a sundog is a parhelion. Ice crystals have to be at the correct angle with the sun.
When the light hits the ice crystals, it is refracted as it passes through, similar to a rain drop in a rainbow.
Depending on the size, shape, and orientation of the crystals, sundogs can have long tails, or rainbow-like effects.
