| Sun dogs, also called mock suns, are colored, luminous spots caused by the refraction of light by six-sided ice crystals in the atmosphere. These bright spots form in the solar halo at points that are 22 degrees on either side of the sun and at the same elevation as the sun. Below is a closeup of a sundog to the left of the sun. |
