They go by many names including ice halos, snow bows, mock suns, phantom suns, or parhelia (the scientific name). The scientific name comes from the Greek word parēlion, meaning “beside the sun.” They occur when sunlight is refracted from ice crystals. The hexagonal shape to ice crystals in the atmosphere act like a prism, refracting and bending the sun’s rays in a horizontal fashion creating the small rainbows.They occur when sunlight is refracted from ice crystals. The hexagonal shape to ice crystals in the atmosphere act like a prism, refracting and bending the sun’s rays in a horizontal fashion creating the small rainbows. They are most commonly seen on very cold days, when there are more ice crystals present in the atmosphere, and at sunrise or sunset when the sun is lower on the horizon.While sun dogs are most common on very cold days, they can happen anywhere and during any time of the year as long as ice crystals are present in the atmosphere, whether suspended in very cold air or in existing in high cirrus
