sixpenceee:A circumhorizontal arc is when an ice-halo is formed by plate-shaped ice crystals in cirrus clouds. The misleading term fire rainbow is sometimes used to describe them. But they are neither rainbows or related to fire. The name comes because it appears to be a rainbow taking the shape of flames in the sky. (Source) -- source link
