At noon on the 16th, a solar halo appeared over the city of Korla, Xinjiang, attracting many local people to watch and take pictures.
Solar halo, also called circular rainbow, is an atmospheric optical phenomenon that is formed when sunlight passes through cirrostratus clouds and is refracted or reflected by ice crystals.
When light enters the ice crystals in the cirrostratus cloud, it undergoes two refractions and disperses into light of various colors in different directions.
