colored spots of light that develop due to the refraction of light through ice crystals
. They are located approximately 22 degrees either left, right, or both, from the sun, depending on where the ice crystals are present. … Sundogs are also known as mock suns or parhelia, which means “with the sun”.

What is a rainbow ring around the Sun called?
A Sun halo
is caused by the refraction, reflection, and dispersion of light through ice particles suspended within thin, wispy, high altitude cirrus or cirrostratus clouds. As light passes through these hexagon-shaped ice crystals, it is bent at a 22° angle, creating a circular halo around the Sun.
How often do Sundogs occur?
They can
occur at any time of the year
and from any place, although they are most visible when the sun is lower on the horizon in January, April, August and October. They also occur when ice crystals in the atmosphere are more common, but can be seen whenever and wherever there are cirrus clouds.

What light property causes Sundogs?
Sundogs are colored spots of light that develop due to
the refraction of light through ice crystals
. They are located approximately 22 degrees either left, right, or both, from the sun, depending on where the ice crystals are present.
Can you see sun dogs in summer?
In summer, a similar effect can be achieved by thin cirrus clouds at 20,000 to 30,000 feet where the air is cold enough that the clouds are made of ice. … The thin clouds allow sunlight to pass through the crystals, which refract the light to make summer sun dogs.
