Transient Luminous Events observed by a pinhole camera E. PONCE1,2, H. SALAZA2, O. MARTINEZ2 1 Department of physics, Moscow State University. The color is believed to be due to a set of blue and near-ultraviolet emission lines from neutral and ionized molecular nitrogen. Transient Luminous Events (TLEs) Halo Ghost Elve Ghost Sprites Blue Jet Blue Starter Secondary Jet Modified version of. English [] Noun []. [17] The jet was located above a thunderstorm over an ocean, and lasted under a second. Here is an example of what to expect from a setup like mine. "[14] They appear to be shorter and brighter than blue jets, reaching altitudes of only up to 20 km. The reason it took so long for these relatives of lightning to be discovered is because they are very short lived (hence the name transient). North is to the left. The term TLE is a broad term encompassing numerous different phenomena with some of the more common ones being sprites, blue jets, and elves. Transient Luminous Events The color abstract images from the Transient Luminous Events series are a direct result of lighting tests for the Time Exposure series. During a very transient time period of ∼1 ms, mostly defined by atmospheric conductivity profile, the electric field can reach values on the order of the critical breakdown threshold field E k at mesospheric/lower iono-spheric altitudes (i.e., E k ’ 217 V/m and 48 V/m at 70 and 80 km, respectively). 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. Red sprites are transient luminous events that on occasion are triggered by lightning activity. Sprites are flashes of bright red light that occur above storm systems. Short-lived luminous electrical manifestations formed in the upper regions of the atmosphere above large thunderstorms. Since then, Eurosprite campaigns have been conducted to observe sprites and other transient luminous events (TLEs), expanding into a network covering large parts of Europe and coastal areas. 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. 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. They were first recorded on October 21, 1989, on a monochrome video of a thunderstorm on the horizon taken from the Space Shuttle as it passed over Australia. Elves are very short lived (~1ms) so they are very difficult to detect with standard 17ms or 33ms temporal resolution video equipment. In addition, I am using another rotor for elevation control. "GJ event that was clearly recorded in eastern China (storm center located at 35.6°N,119.8°E, near the Huanghai Sea)". I wanted in some way to contribute to the TLE research effort. In 2009 through 2013, the number of optical observations of TLEs reached a peak of 2000 per year. I have spoken with a researcher in this field and he has told me that he recommends F1.2 or F1.4 lenses for the Watec 902H. 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. [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.
