A fire rainbow forms in cirrus clouds.

However, there is no fixed position in the world where the phenomenon may take place.

Why is a fire rainbow rare?

The cirrus cloud formations and sun being at the correct angle and the hexagonal ice crystals being arranged in the perfect way is quite unusual.

The difference between a rainbow and a fire rainbow

Fire rainbows, however, do not form because of refraction from water droplets. They form when light from the sun is refracted through ice crystals found in cirrus clouds.
