Sun dogs versus Rainbows

A Sun Dog captured in Bolton, featured on the Weather Network.

On Friday, our department’s own Dr. Lee witnessed a Sun Dog on her way to York, an atmospheric phenomenon that Dr. Klaassen explains,  “…they form about 22 degrees on either side of a bright sun, due to refraction by ice  crystals. If you are looking at a rainbow, the sun is behind you”.
