Trivia : Atmospheric Optical Phenomena; Halo ( Moon Halo & Sun Halo ) Halos are caused by cirrus clouds. Sunlight through the ice crystals causes the light to split, or be refracted. When at just the right angle, it causes us to see the halo. The same thin clouds can cause a ring, or halo, around the moon at night. What does it mean when you see a halo around the sun? When you see a halo around the sun, that is an indicator that there is moisture high in the atmosphere. If the halo is followed by high, thin, wispy cirrus clouds, then there is a storm system approaching you. It's typically 24 to 48 hours away.
