Sundog


    The other day when we were doing our morning walk on the Loop Trail, we noticed that a bright “Sundog” just above the peak of one of the mountains in the Cariboo Range.  A sundog is a rainbow-colored patch of light that appears on the left, right, or both sides of the sun at 22°, when the sun is low on the horizon—just after sunrise or before sunset, for instance. 

    Sundogs are created by light being prism-split into colors, when it passes through plate-like ice crystals in high cirrus clouds.   The red band is on the side nearest the sun.  They can appear worldwide at anytime of year, but are most commonly seen during the winter.

    In the past when they were very bright, some people reported that there were three suns in the sky.
