On OctoTLEs were recorded during orbits 44 and 45. The next known video recordings of a TLE were taken in 1989, when the Shuttle Mission STS-34 was conducting the Mesoscale Lightning Observation Experiment. When reviewing the video taken, two finger-like vertical images appeared in two frames of the film. The first video recording of a TLE was captured accidentally on Jwhen researcher R.C Franz left a camera running overnight to view the night sky. TLEs generally last anywhere from less than a millisecond to more than 2 seconds. TLEs are secondary phenomena that occur in the upper atmosphere in association with underlying thunderstorm lightning. The acronym ELVES (“ Emission of Light and Very Low Frequency perturbations due to Electromagnetic Pulse Sources”) refers to a singular event which is commonly thought of as being plural. Other types of TLEs include sprite halos, ghosts, blue jets, gigantic jets, pixies, gnomes, trolls, blue starters, and ELVESs. C-sprites exhibiting tendrils are sometimes called “carrot sprites”. C-sprites (short for “columniform sprites”) is the name given to vertical columns of red light. Sprites are flashes of bright red light that occur above storm systems. There are several types of TLEs, the most common being sprites. Transient luminous events have also been observed in far-ultraviolet images of Jupiter's upper atmosphere, high above the altitude of lightning-producing water clouds. The preferred usage is transient luminous event (TLE), because the various types of electrical-discharge phenomena in the upper atmosphere lack several characteristics of the more familiar tropospheric lightning. Upper-atmospheric lightning is believed to be electrically induced forms of luminous plasma. Upper-atmospheric lightning and ionospheric lightning are terms sometimes used by researchers to refer to a family of short-lived electrical-breakdown phenomena that occur well above the altitudes of normal lightning and storm clouds.
