Cirrostratus clouds are thin, generally uniform clouds, composed of ice-crystals. They are difficult to detect and if capable of forming halos the cloud takes the form of thin cirrostratus nebulosus. Its presence indicates a large amount of moisture in the upper atmosphere. Cirrostratus clouds sometimes signal the beginning of a warm front if they form after cirrus and spread from one area across the sky and thus may be signs that precipitation might follow in the next 12 to 24 hours.

Anyone else see this? Awesome circumhorizontal arc over Siesta Key Beach this afternoon! It's essentially an ice-halo formed by the refraction of sunlight in plate-shaped ice crystals suspended in the atmosphere. They are most commonly spotted in cirrus or cirrostratus clouds 3/30/17

The "halo cloud" was just an optical illusion caused by sunlight hitting a cloud at just the right angle. The cloud's round shape is likely what is known as a hole-punch cloud. These clouds occur within cirrostratus clouds, which are often composed of ice crystals and drops of water that are below freezing temperature but still in liquid form. When cirrostratus clouds are disturbed by planes or strong winds, the droplets can freeze instantly or evaporate, the latter of which will form the…

Why I want to go to Finland :) These are sun halos, which are produced by the ice crystals in cirrostratus clouds.

Its called a 22° halo (around the sun or moon) and is caused by tiny ice crystals contained in the high cirrostratus clouds... Sometimes one can see more than one ring :-)
