‘Fire rainbows’ are created from ice!


‘Fire rainbows’, technically known as circumhorizontal arcs, occur from a spectacular phenomenon in the sky. They are formed by the refraction of sunlight or moonlight on plate-shaped ice crystals in the clouds high up in the sky. They are neither fire nor rainbow, yet are called so because of the vibrant colours that spill out in different directions making them appear like flames.
