Capturing a Sundog

$Sundogs appear when sunlight passes through a thin veil of ice crystal clouds (usually cirrus or cirrostratus), and the ice acts as a prism, refracting the light. A sundog is seen about 22 degrees to the left or right of the Sun. Sundogs often form in pairs on either side of the Sun. NCJ photo by Cathy Cook$
