A sun dog (scientific name parhelion, plural parhelia, from Greek parēlion (παρήλιον) from παρά (beside) + ἥλιος (sun), "beside the sun"; also called a mock sun or a phantom sun is an atmospheric phenomenon that creates bright spots of light in the sky, often on a luminous ring or halo on either side of the sun. Sundogs may appear as a colored patch of light to the left or right of the sun, 22° distant and at the same distance above the horizon as the sun, and in ice halos.
