Have you ever looked up and noticed that there’s a big ring around the Sun? These rings are caused by ice crystals within thin cirrus clouds, and there several different kinds of sun rings you can see depending on the weather conditions.









One of the most common ones is called a 22° halo. They get this name because the ring is located 22 degrees away from the Sun itself. Both the Sun and the Moon block a 1/2 degree region of the sky at a time, so the ring around the Sun is about 44 times larger than the Sun itself.
