The 7 Most Bizarre Natural Phenomena Caught on Camera
A circumhorizontal arc is an ice-halo formed by the refraction of sun- or moonlight in plate-shaped ice crystals suspended in the atmosphere, typically in cirrus or cirrostratus clouds. As with all halos, it can be caused by the Sun as well as the Moon. The misleading term "fire rainbow" is sometimes used to describe this phenomenon, although it is neither a rainbow, nor related in any way to fire. More

The "halo cloud" was just an optical illusion caused by sunlight hitting a cloud at just the right angle. The cloud's round shape is likely what is known as a hole-punch cloud. These clouds occur within cirrostratus clouds, which are often composed of ice crystals and drops of water that are below freezing temperature but still in liquid form. When cirrostratus clouds are disturbed by planes or strong winds, the droplets can freeze instantly or evaporate, the latter of which will form the…

A sun dog, or parhelion, is an exceedingly bright spot on a solar halo. A sundog is an atmospheric optical phenomenon primarily associated with the reflection or refraction of sunlight by small ice crystals making up cirrus or cirrostratus clouds. Often, two sun dogs can be seen (one on each side of the sun) simultaneously.
