There are also rare phenomena to take account of, like cloud bows, which are the very pale rainbows you might see from the window of a plane, and things which are hard to see, like supernumerary rainbows.

what is believed to be the first photographic recording of a quaternary rainbow in nature. It appears on the Sun side of the sky with its red arc at a radius of about 45° from the Sun. The original pictures have been subjected to various forms of image processing to reveal the tertiary rainbow as well as the quaternary rainbow.
