Altho I am old and I have lived in northern Illinois most of my life, I have only heard of SUN dogs. Also, I was told as a youngster that there is weather folklore around sun dogs, i.e., a change in the weather. Do YOU have a comment? Thank you... Dean
Hi, Dean, Yes...Sun dogs, also called mock Suns or parhelia, look like second Suns in the sky, appearing at the same height of the Sun and to its right and/or left by 22 degrees or more. They are caused by light that is refracted through ice crystals in the atmosphere (as through a prism) and exhibit the colors of the rainbow.
