Fire Whirls
The fire whirl, fire devil, or fire tornado, is a rare natural phenomenon. It occurs when a fire, combined by certain air temperature and currents, forms a whirl that rises into the air like a tornado. They can be actual whirlwinds that disengage from the flames, or else can become a vortex of flame. The fire whirl usually occurs during bush fires.
Moonbows
The closest relative to a rainbow, the moonbow (or lunar rainbow) is a formation of water droplets, mist, and light. Unlike a rainbow, a moonbow is produced by light reflected from the moon, which mingles with the droplets of water and spraying mist, usually from a waterfall.
Because of the faint light emitted from the moon, moonbows are extremely elusive, and their colors hard to discern. However, there have been many sightings, particularly at Yosemite Falls in California, Cumberland Falls in Kentucky, Victoria Falls in Zambia/Zimbabwe, and Waimea in Hawaii.
Moonbows are also easily viewed when the moon is full, and can also be produced when the moon is low in the sky, and the rain is falling opposite.
