How rare is a fire rainbow?
As mentioned above, fire rainbows are rare. The source of light—the Sun (or Moon)—needs to be at least 58o above the horizon, meaning that fire rainbow is almost impossible to see in places north of 55oN or south of 55oS. Also, in places where it is spotted, its frequency of occurrence and duration varies widely.
What are fire rainbows called?
