Fire rainbow or in a more accurate term, circumhorizon arc, is basically an ice halo formed by ice crystals located very high, in the cirrus clouds. It is one of totally awesome natural phenomena that you probably didn't know about. This huge flamboyant lovely display of colors is really not as rare as you might think, and how often it appears depends mostly on location, and especially latitude. For example, in the US it can be seen several times a summer in each year in the same place, but in Central or Northern Europe it’s very rare and not in any non four seasoned countries such as Malaysia. Of course, this rainbow is not formed the way ‘classic’ rainbows are formed. Light passes through the hexagonal ice crystals via a vertical side and leaves through the nearest horizontal bottom face. If there alignment is just right, it makes the whole cloud shine rainbow-colored.
