Photographer's Note

A sundog is a rainbow-like spot in a cirrus cloud. Cirrus clouds are mostly tiny particles of ice, shaped like hex bathroom tiles or stubby pencils each no bigger than the tiniest grains of sand. When the crystals line up like tiles on a table, they bend the light 22 degrees as the light enters and exits the crystal. Light colours fan out from the bending and display as a sun-dog. They usually appear in pairs two hand-breadths on either side of the sun when it rises or sets behind a very thin veil of high cirrus clouds.

Sun-dogs are among the most commonly seen sky phenomena, appearing most prominently when the sun is low. They are reddish on the side facing the sun and often have bluish-white tails stretching horizontally away from them.
