The formation, scientists explain, is called a Fallstreak Hole. It forms when airplanes fly through thick clouds causing the water particles to freeze in mid-air as they fly next to the aircraft. This Fallstreak Hole is certainly not the first, in fact, apart from the one over Wonthaggi, in Victoria, there was another sighting of such a phenomenon in Perth this October.
Those not familiar with such a formation feared that the bizarre cloud may have been a “Rapture” cloud.
However, Michael Efron, duty forecaster with the Meteorology Bureau assured the public that the peculiar cloud could have been a Punch hole cloud. He added that they form through phenomena called “seeding”, when aircrafts break through clouds causing water to freeze up as it flies by the plane.
“They form when the water temperature in the cloud is below freezing, but the water has not yet frozen due to a lack of ice nucleation particles,”
Mr. Efron said.
“In this case, when the water does start to freeze, it falls down to the surface … so you’re left with this cloud surrounding it, this clear area.”
When viewed from different angles, it seemed like the peculiar cloud was surrounded by a rainbow, which Mr. Efron explains, is called iridescence. This common phenomenon occurs in other natural objects such as soap bubbles or seashells.
Conspiracy theories didn’t fail to appear as witnesses were joking about alien motherships and other inexplicable events. Twitter was also full of comments about government conspiracies and different wormhole travel tests.
However, the stir-up is only due to the scarcity of the event. Would Fallstreak Holes occur as often as rainbows, there would no longer be such turmoil.
