Mysterious glow in the sky scared the Italians
(ORDO NEWS) — Photographer-naturalist Walter Binotto published a picture of a glowing disk in the sky.
For a long time, no one could understand what kind of glow it was and how it arose. It seems that some eyewitnesses even believed in aliens… Nevertheless, there is no mysticism in this mysterious phenomenon.
What is this
The Italians saw the so-called “elf” (from the English ELVES, that is, Emission of Light and Very Low Frequency perturbations due to Electromagnetic Pulse Sources – “light emission and very low-frequency disturbances due to a pulse from an electromagnetic source”).
This is a rare type of stratospheric or mesospheric disturbance resulting from intense electrification during a thunderstorm.
Disc-shaped regions form when electromagnetic pulses emitted by lightning enter the Earth‘s ionosphere and affect its upper atmosphere.
They usually occur between 80 and 644 km above the ground and can be hundreds of kilometers in diameter.
As a rule, “elves” are only visible to satellites orbiting the Earth. According to Spaceweather.com, Binotto’s new image is likely the best image of the phenomenon ever taken from the surface of our planet.
