A secondary rainbow, at a greater angle than the primary rainbow, is often visible. The term double rainbow is used when both the primary and secondary rainbows are visible. In theory, all rainbows are double rainbows, but since the secondary bow is always fainter than the primary, it may be too weak to spot in practice.
Double rainbow and supernumerary rainbows on the inside of the primary arc. The shadow of the photographer's head marks the centre of the rainbow circle ( antisolar point ).

University of Hawaii sports teams are even named after rainbows. “For me, rainbows really signify hope and new beginnings,” said Liane Usher, the president of the Children's Discovery Center in Honolulu, which features rainbows on its ...
In secondary rainbows, that order is reversed with violet coming first from top to bottom. A secondary rainbow is much fainter than a primary one because the intensity of light is reduced.
Two sun dogs often flank the Sun within a 22° halo. The sun dog is a member of the family of halos caused by the refraction of sunlight by ice crystals in the atmosphere. Sun dogs typically appear as a pair of subtly colored patches of light, around 22° to the left and right of the Sun, and at the same altitude above the horizon as the Sun ...
It takes all the colors of the rainbow for us to see it that way. It happens because of something called the Rayleigh effect, or Rayleigh scattering, named after a British scientist who first ...
