Halos imaged by Kimberly MacLin (site) in Southern Minnesota on the Winter Solstice, December 21. ©M Kimberly MacLin, shown with permission.

The icy sun is flanked by diamond dust sundogs each tapering away into a 22 degree halo.

A faint parhelic circle courses across the sun parallel to the horizon. Perpendicular to it are upper and lower sun pillars.

A classic display.
