This was observed for example in the entry of meteors in its orbit to be attracted lightning. Then barreled flashes can form also in higher layers. Sprites occur in classic, more line-like structure like normal lightning flashes then particularly easy when a channel is pre-ionized air. Leprechauns are about 100 - to 1000-times more intense than typical flashes and cover partly widths of up to 50 km and can be during discharge divided into several areas. Most goblins are columnar, sometimes they look like a mushroom cloud. Sprite, spirit ',' puck ') is referred to in meteorology a flash that reaches an altitude of 100 kilometers, beats up during a thunderstorm above the clouds.

Since these flashes are difficult to observe from the ground, there was a long few photographs of it until targeted recordings from 1989 - primarily from airplanes and space shuttles - have been made. The result was that pilots concealed many such observations in the sequence. The phenomenon has been discovered at the beginning of aviation, but often dismissed as spinning of pilots. In this way, about 80 kilometers above the ionosphere, an electrically conductive layer in hundreds of kilometers up gradually in the near-Earth space. It has long been known that the ultraviolet radiation from the Sun ionizes the air molecules far beyond the turbulent layers of the atmosphere, ie knocks electrons out of them. In retrospect is amazing that you have not discovered this earlier events actually should have been expected lightning-like luminous phenomena at the highest altitudes of the atmosphere almost. Thus it is clear that not only spectacular lightning flashes in the lowest layers of air between thunderclouds and the ground back and forth: Often there are discharges in the thin air layers up to 90 kilometers above the clouds. Since then it has - from the space shuttle, aircraft and from the ground - seen hundreds of them. Now began active efforts to document such discharges in the upper envelope of air. The images revealed flashes of a completely new type. Winckler and his team at the University of Minnesota in Minneapolis in 1990 for the first time one of the most puzzling phenomena with the video camera held fast. Most scientists took these reports seriously - to John R.
