What is this strange light tornado twisting within a thunderstorm cloud over Greenwood, Indiana?
Is this HAARP? An alien spaceship refueling over the clouds? Or just an another intriguing natural sky phenomenon?
As explained by Reddit, this strange sky phenomenon you are seeing is:
[quote_box_center] sunlight reflecting off ice crystal faces that are constantly being oriented by the developing electric field just above the [cumulonimbus] top. Then there is a discharge in the cloud, and the field collapses momentarily, and the crystals begin to realign again. Then this just keeps happening over and over.[/quote_box_center]
The phenomenon is called “crown flash” or “leaping sun dog”.
