Sundog at Old Crow, Yukon, Canada imaged by Kai Rannik. Old Crow (Home of the Vuntut Gwitchin) is north of the Arctic Circle on the confluence of the Crow and Porcupine Rivers.  When this image was taken near noon on January 29th, 2003 the sun was not quite 3° high and the temperature was a numbing minus 42°C. The bright sundog is formed by diamond dust plate crystals. Above it curves a fragment of a 22° halo. Stretching horizontally from the sun the parhelic circle characteristically brightens beyond the sun dog. A thin pillar reaches upward from the sun. ©2003 Vuntut Gwitchin First Nation, shown with permission.
