Large gaps between high clouds, or cloud holes, are observed in some areas of Victoria.
The cloud hole phenomenon appeared in the Gippsland area, eastern Victoria state, from about 1pm on November 3.
A cloud hole is a large gap that appears between high clouds such as cirrocumulus or altocumulus in the sky.
When part of the cloud begins to freeze, ice crystals begin to fall and create holes, usually circular, in the cloud.
Turbulence in the cloud layer caused by external factors can affect the chain evaporation effect, causing water vapor to freeze and fall, creating large gaps between the clouds.
According to scientists, this is a relatively rare phenomenon. Because cloud holes are rare, this phenomenon can be confused with an unidentified flying object (UFO).
Colorful reflective cloud holes appear in the sky over the town of Trafalgar.
The image of the cloud hole was observed by local people from the area between the towns of Leongatha and Korumburra.
