Sun dog millionaire
A sun dog or sundog (scientific name parhelion, from the Greek ±è²¹°ùŧ±ô¾±´Ç²Ô - meaning 'beside the sun'; also called a mock sun) is an that creates bright spots of light in the sky, often on a luminous ring or halo on either side of the sun.
Halos around the Sun are formed by light being reflected and refracted by ice crystals in thin high clouds such as cirrus.
In addition to circular halos, ice crystals can also produce various arcs (partial circles like rainbows) and parhelia (also called mock suns or sun dogs).
Sun dogs may appear as a coloured patch of light to the left or right of the sun.
They can be seen anywhere in the world at any time of the year and are best seen when the sun is low.
