Residents in El Dorado County looked up on Tuesday to see the sun encircled by a rainbow for a short period of time.

Called a 22 degree halo or sun halo, National Weather Service meteorologist Drew Peterson said it’s caused by millions of hexagonal ice crystals randomly oriented in the atmosphere. When light from the sun passes through them, it is refracted, causing a dark space around the sun and then a ring of light.

Similar rings are occasionally formed around the moon and are called moon rings or winter halos.
