A halo to one side of the sun, with cirrus clouds


A small halo formed by cirrus clouds. The sun is below the arc of the halo shaded by the leaves. Haloes are formed by refraction of the sun’s rays by the ice crystals of the cirrus clouds. They usually form an arc at an angle of 22 degrees to the sun though under certain conditions this can be variable. Haloes can appear and disappear very rapidly as the clouds forming them move across the sky. The type of clouds in this image are sometimes called ‘mare’s tails’ or ‘fallstreaks’.
