; Bonfond, Bertrand; Gladstone, R.G. Below is an example of a possible blue starter which I imaged on Oct 14, 2009. [6] The phenomena were named after the mischievous sprite, e.g., Shakespeare's Ariel or Puck,[7] and is also an acronym for Stratospheric/mesospheric Perturbations Resulting from Intense Thunderstorm Electrification. Another type of TLE that can be imaged above storms is the blue jet. Elves can be identified by their donut shape and as can be seen here the area covered by this elve is immense! #TLES.

This paper gives an introduction to what is meant by "Education and Public Outreach (EPO)", and emphasizes the usefulness and effectiveness of such activities in scientific projects. Upper-atmospheric lightnings sometimes resemble the shape and appearance of different UFO phenomenas. They were later dubbed 'pixies'. Below is a descrition of each of the events: Sprites: They initiate between 65 and 85 km in altitude and are typically … ", "UPWARD ELECTRICAL DISCHARGES FROM THUNDERSTORM TOPS", Homepage of the Eurosprite campaign, itself part of the CAL (Coupled Atmospheric Layers) research group, March 2, 1999, University of Houston: UH Physicists Pursue Lightning-Like Mysteries, Ground and Balloon-Borne Observations of Sprites and Jets, Sprites and ELVES : Lightning's strange cousins flicker faster than light itself, Sprites, jets and TLE pictures and articles, High speed video (10,000 frame/s) taken by Hans Stenbaek-Nielsen, University of Alaska, NASA Astronomy Picture of the Day: Gigantic Jets Over Oklahoma (August 29, 2007). ; Bonfond, Bertrand; Gladstone, R.G. Blue jets are believed to be initiated as "normal" lightning discharges between the upper positive charge region in a thundercloud and a negative "screening layer" present above this charge region. C-sprites (short for “columniform sprites”) is the name given to vertical columns of red light. Blue starters are believed to be blue jets that don’t quite make it. Halos are another similar phenomena which are more closely related to sprites and are thought to be associated with electrical breakdown in sprites due to the thundercloud quasi-electrostatic (QE) field. My experience with the VLF portion of this project is documented in my SID Receiver page. The term TLE is a broad term encompassing numerous different phenomena with some of the more common ones being sprites, blue jets, and elves. The majority of these images, which include the first color imagery, are associated with a single thunderstorm. Sprites were predicted to exist in 1925, and there had been reports of strange flashes above thunderclouds for centuries before that, but the first image of a sprite wasn’t captured until 1989. In this video, i am explaining Transient Luminous Events such as Sprites, Blue Jets, Halos, Ghosts, Gigantic Jets Etc. Check out Transient Luminous Event by Bogdo Ula on Amazon Music. Their color is unknown as they have only been observed in black-and-white footage. [24] From 35 miles, Holmes's video shows a blue streamer reach up from the top of a thunderstorm to the ionosphere, becoming red at the top. The positive end of the leader network fills the negative charge region before the negative end fills the positive charge region, and the positive leader subsequently exits the cloud and propagates upward. Specimens : Transient Luminous Events in the Mesosphere. The term TLE is a broad term encompassing numerous different phenomena with some of the more common ones being sprites, blue jets, and elves. [22], On March 28, 2017, Photographer Jeff Miles captured four gigantic jets over Australia.[23]. Sprites are large-scale electrical discharges which occur high above a thunderstorm cloud, or cumulonimbus, giving rise to a quite varied range of visual shapes. Sprites are brief large-scale electrical discharges that occur high above thunderstorm clouds giving rise to a varied range of visual shapes flashing in the sky. I wanted in some way to contribute to the TLE research effort. Simply recording hours of boring dimness with the occasional lightning flash and then analyzing all of this would be a tedious task indeed. [1992], (d) one of the first recordings of a jet (from Figure 3 of Wescott et al. These mysterious phenomena are known as Transient Luminous Events (TLEs), and are usually invisible to the naked eye because they happen on millisecond timescales, too fast to be seen. TROLLs, (Transient Red Optical Luminous Lineaments) occur after strong sprites, and appear as red spots with faint tails, and on higher-speed cameras, appear as a rapid series of events, starting as a red glow that forms after a sprite tendril, that later produces a red streak downward from itself. Blue jets and blue starters are rare, most likely because since they are blue in color most of their light gets filtered out by the atmosphere at large distances. Click on the image to get another blue jet/starter example from Sep, 05 2010 as well. 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.[1][2]. [9] Sprites have been held responsible for otherwise unexplained accidents involving high altitude vehicular operations above thunderstorms.[10]. Below is a descrition of each of the events: Sprites: They initiate between 65 and 85 km in altitude and are typically triggered by a positive cloud-to-ground lightning strike. It was put together for educational purposes. The color is believed to be due to a set of blue and near-ultraviolet emission lines from neutral and ionized molecular nitrogen. See more ideas about nature, beautiful nature, scenery. Installing a highly sensitive low light camera outside is only half of the problem. Lightning is an extremely energetic electric discharge process in our atmosphere that remains an enigma to date despite intensive research. [4][5] In ensuing decades, high altitude electrical discharges were reported by aircraft pilots and discounted by meteorologists until the first direct visual evidence was documented in 1989. Also tendrils can be seen below the main sprite bodies reaching many miles downward, but not getting near the thunderstorm top. These mysterious phenomena are known as Transient Luminous Events (TLEs), and are usually invisible to the naked eye because they happen on millisecond timescales, too fast to be seen. A team of NASA scientists has spotted strange flashes known as "transient luminous events" (TLEs) in the upper atmosphere of Jupiter. Elves are very short lived (~1ms) so they are very difficult to detect with standard 17ms or 33ms temporal resolution video equipment. On November 10, 2012, the Chinese Science Bulletin reported a gigantic jet event observed over a thunderstorm in mainland China on August 12, 2010. Spectacular sprites are detected by use of their characteristic signatures following the continuing current of their parent positive cloud to ground lightning discharges which are recorded with a global network of four radio receivers operating at a frequency range from ~1-1000 Hz. [26] This refers to the process by which the light is generated; the excitation of nitrogen molecules due to electron collisions (the electrons possibly having been energized by the electromagnetic pulse caused by a discharge from an underlying thunderstorm). Gigantic jets between a thundercloud and the ionosphere. Assista o deslocamento da frente do temporal chegando a Morro Reuter no domingo a tarde. They are mostly red in color due to the breakdown of the rarefied air high above the storm and the fact that nitrogen glows red when exited by low energy electrons in this type of discharge. Here is another sprite group taken on Nov 5, 2009 on which I used UFOAnalyzer to calculate the distance to each sprite from my viewing location. FRANKIE LUCENA'S TLE chart Gigantic Jet … So it is worth the money. To the right is a bright “jet” like protrusion that could very well be a blue starter (labeled red). Also seen (faintly) are green emissions from excited oxygen in the sprite tops ( GHOSTS ). Formosat-II isual about Transient Luminous Events. This is very important when using higher focal lengths like 16mm lenses for example. This plot reinforced the circular pattern seen on the image. "GJ event that was clearly recorded in eastern China (storm center located at 35.6°N,119.8°E, near the Huanghai Sea)". transient luminous event (plural transient luminous events) ( astronomy , meteorology , aviation ) Any of a variety of upper atmospheric optical phenomena associated with thunderstorms. In particular, we suggest that these are elves, sprites or sprite halos, three types of TLEs that produce spectacular flashes of light very high in the Earth's atmosphere in response to lightning strikes between clouds or between clouds and the ground. In particular, we suggest that these are elves, sprites or sprite halos, three types of TLEs that produce spectacular flashes of light very high in the Earth's atmosphere in response to lightning strikes between clouds or between clouds and the ground. Jump to navigation Jump to search. It’s possible that this “jet” reached higher than the image shows, but due to the great distance (70 miles) all but the brightest sections reached my location. Transient luminous event telescope system Showing 1-2 of 2 messages. Electrostatic Detection of Lightning and Transient Luminous Events. Stars down to magnitude 7.3 can be discerned in this image.
