Wikopedia says "Sundogs typically, but not exclusively, appear when the is low, e.g. at sunrise and sunset, and the atmosphere is filled with ice crystal forming cirrus clouds, but diamond dust and ice fog can also produce them. They are often bright white patches of light looking much like the sun or a comet, and occasionally are confused with those phenomena. Sometimes they exhibit a spectrum of colours, ranging from red closest to the sun to a pale bluish tail stretching away from the sun.[1] White sundogs are caused by light reflected off of atmospheric ice crystals, while coloured sundogs are caused by light refracted through them. White sundogs are also thought to be caused by the light from the sun reflecting off of water on the ground and focusing the reflected light on the clouds above."
I never remember seeing them as a child, but once I married and moved "up north" they were an every winter occurance.
