A bizarre, glittering cloud with a strip of rainbow across it has appeared in the skies over Australia – and no, it isn’t chemtrails or a UFO.
Residents of the Gippsland area in the east of Victoria state were baffled and blown away in equal measure to see the unusual cloud formation, which appeared at around 1pm local time on Monday.
To the disappointment of conspiracy theorists and UFO enthusiasts, the circular band in the cloud with the rainbow belt was revealed to be a Fallstreak Hole, also known as a hole-punch cloud or (most theatrically) a skypunch.
According to the Cloud Appreciation Society, the holes are formed when water droplets in the cloud freeze into ice crystals, becoming slightly heavier than the surrounding droplets and pulling a portion of the cloud downward. The rainbow effect is the result of those frozen crystals refracting light.
