One explanation for the enigmatic bursts at high altitude mistaken for UFOs

"Winter sprites"

LONDON - For those who believe in the apparitions of flying saucers, commonly known as UFOs, there's bad news. In addition to the explanations given so far of the various phenomena seen in decades is now added that of Professor Colin Price, University of Tel Aviv. Price, head of the department of geophysics and planetary sciences, is a specialist of the "winter sprites" that appear in the skies of the northern hemisphere winter months. The Sprites are large electrical discharges that occur above the storm clouds and occur in clusters at heights between 50 and 100 km, and sometimes beyond.

spirits of the air - The Sprites are the spirits of the air "and the term was taken from" Dream of a Midsummer Night "by Shakespeare. The phenomenon was photographed for the first time in 1989 by scientists at the American University in Minnesota. Their demonstrations take place, therefore, very high in the sky, in the upper atmosphere. "They are usually triggered lightning storms in the normal lower levels to stimulate the higher electric field producing the Sprites and now we discovered that only certain types of lightning can trigger them - explains Price - How this happens is still not well understood and debate is open but it certainly can explain some peculiar observations of UFOs. "

"Elves" - The Sprites are sometimes associated with other phenomena such as 'elves' luminous halo with a diameter of about 400 km. Such formations often move in the bright sky and this is the reason why they were called spirits of the air or elves. And it is another of their characteristics associated with UFOs. The strange lightning reaching very high altitudes can have an impact on the ozone layer that surrounds the Earth protecting life. "Fortunately note - Price - that does not happen very often and therefore their potential damage is contained. But given the risk posed should investigate them better. "
