Sprites —The most common TLE is a flash of red light directly above large thunderstorms. Andreas aimed for cloud turrets – cloud pillars extending into the upper atmosphere – and shot a 160 second video showing 245 blue flashes from the top of a turret that drifted from the Bay of Bengal’s thunderstorm. NASA is investigating cloud top lightning phenomena, which includes red sprites, blue elves, and gamma ray bursts, with sensors on the International Space Station.

For years, their existence has been debated - elusive electrical discharges in the upper atmosphere that sport names such as red sprites, blue jets, pixies and elves. Exiter 6. They are most frequently seen in the Midwest. Most satellites orbit around 800 km in altitude, making them unsuitable for this type of observation. This region spans most of the mesosphere, the region of the atmosphere between about 50 and 80 km (30 and 50 miles) in altitude and which overlaps much of the ionospheric D region (between 70 and 90 km, or approximately 40 and 55 miles in altitude). Beginning in 1990, about twenty images have been obtained from the space shuttle. Blue jets are hard to study from the ground, being at lower altitudes than sprites. Elizabeth Howell Space.com Contributor. Let us know if you have suggestions to improve this article (requires login).

They’re blue due to ionised emissions from nitrogen. Thank you for liking. Red sprites and blue jets are upper atmospheric optical phenomena associated with thunderstorms. Blue jets are best studied from aircraft, but those flights are costly. Blue jets are hard to study from the ground, being at lower altitudes than sprites. Known by different names, red sprites, blue jets and elves are hard to document, lasting on average less than 20 miliseconds. The results of this portion of the Thor experiment were published recently: Chanrion, O., Neubert, T., Mogensen, A., Yair, Y., Stendel, M., Singh, R., & Siingh, D. (2017). The first images of a sprite were accidently obtained in 1989. 0. log in. So we must wait to learn more about blue jets. Blue jets are found up to 50 km altitude with Red Sprites occurring between 60-80 km altitude. join. A SpaceX Dragon made it into orbit earlier this month carrying a new scientific lab designed to track some of the most mysterious atmospheric phenomena: red sprites, blue jets, and ELVES. As part of his 10-day mission Andreas performed an experiment called Thor after the god of thunder, lightning and storms in Nordic mythology. Red sprites and blue jets are the signatures of this "space lightning." Watch the video above to see Mogensen’s footage, and learn more about blue jets, red sprites and other flashes … The ISS offers an optimal observation point with its low orbit available at around 400 km altitude. The bright area beneath the sprite is an overexposure of normal lightning occurring at the thunderstorm's cloud top which is 55,000 feet high. Red sprite over Oklahoma, caught by Paul Smith on October 6, 2017. In ensuing decades, high altitude electrical discharges were reported by aircraft pilots and discounted by meteorologistsuntil the first direct visual evidence was documented in 1989. ESA astronaut Andreas Mogensen (who happens to the first astronaut from Denmark) was tasked during his mission on the International Space Station (ISS) with documenting red sprites and blue jets in order to understand more about them. Red Sprites/Blue Jets by Wonder Council, released 02 February 2015 1. Red sprites have a reddish colour on low-light television records, and blue tendrils have been observed trailing beneath them. 9 words related to lightning: chain lightning, forked lightning, atmospheric electricity, bolt, bolt of lightning, thunderbolt, flash, heat lightning.... What are synonyms for Red Sprites and Blue Jets? But elves … Reply. They occur when positive lightning goes from the cloud to the ground. Blue jets are cones of blue light brighter than sprites that spray upward from the tops of thunderclouds up to an altitude of about 25 miles (40 kilometers) at … Corrections? Wilson predicted that electrical breakdown should occur in the atmosphere high above large thunderstorms. The bizarre discharges have been called red sprites, blue jets, pixies and even elves. Transient Luminous Event (TLE) are flashes and glows that appear above storms that are results of activity occurring in and below those storms. The image shows lightning strikes illuminating clouds over Western Australia during a thunderstorm. Lightning phenomena: sprites, elves and blue jets There are different types of lightning (or electrical discharges) that occur well above the realm of the thunderstorms that we experience in the troposphere (the lowest layer of earth’s atmosphere as it runs as high as about 17 km above earth’s surface). Also, blue light doesn't travel through the air as well as red, and high-speed cameras are less sensitive to blue. The photo above was taken by an astronaut on board the space shuttle and shows what has become known as a red sprite.

Chasing Red Sprites and Blue Jets: Photos Jason Ahrns, a graduate student at the University of Alaska-Fairbanks, goes sprite-chasing at night during electrical storms. Explanation of Red Sprites and Blue Jets They are usually triggered by the discharges of positive lightning between an underlying thundercloud and the ground. Blue jets happen in cone shapes above thunderstorm clouds, and are not related to lightning. Red sprites are interpreted as the downward streamers of varying cross sections launched from plasma patches in the lower ionosphere, which are caused by the electric field generated by the lightning discharge. Although scattered sightings of these fleeting emissions had been reported for more than a century, it wasn't until about 5 years … The first of these emissions, dubbed ‘‘sprites,’’ are luminous red structures that typically span the altitude range 60–90 km, often with faint bluish tendrils dangling below.
