It was a magnificent, mysterious, borderline-miraculous sight, and the group of citizen skywatchers who witnessed it decided to give the phenomenon a fittingly majestic name: "Steve. 24 APRIL 2017. Receive mail from us on behalf of our trusted partners or sponsors? Finally, they are answering some of their questions, and it turns out STEVE … What causes these ghostly lights is still a … Writing in the journal Science Advances in March, researchers (including Gallardo-Lacourt) decided to keep the name "Steve" as the official nomenclature for the colorful happening, but they changed it to an acronym standing for "Strong Thermal Emission Velocity Enhancement" — aka STEVE. She also included GPS coordinates from Vimy, Alberta, that helped Donovan link the data to identify the phenomenon. Contrary to the findings from the Steve study published earlier this year, the satellite did not detect any charged particles raining down toward Earth's magnetic-field lines, indicating that whatever created Steve did not follow the same rules as the solar particles that create the aurora. Steve is an atmospheric optical phenomenon which appears as a purple and green light ribbon in the sky, formally discovered in late 2016 by aurora watchers from Alberta, Canada. When a European Space Agency satellite passed directly through Steve in July 2016, instruments on board confirmed that a pipeline of incredibly fast, ridiculously hot gas was slicing through the atmosphere there. They found that the mauve arch occurs when charged particles are heated high up in the earth’s atmosphere. Turbulent eddies and whirls dump some of their energy into the green cannonballs.” This idea may explain their pure color. Short for Strong Thermal Emission Velocity Enhancement, this strange aurora has puzzled scientists for years. While looking like a family … New research into a strange atmospheric effect known as STEVE has failed to associate its enigmatic lights with aurora, pointing to the presence of an entirely new type of atmospheric phenomenon.

In the new University of Calgary study, Gallardo-Lacourt and her colleagues decided to use the data recorded that night to further investigate Steve's mysterious origins. Now, scientists understand that the elements of a STEVE originate from two distinct atmospheric phenomenon, writes Toshi Nishimura, a space physicist at … According to Gallardo-Lacourt, that's "completely unknown." 25, 2019 — The celestial phenomenon known as STEVE is likely caused by a combination of heating of charged particles in the atmosphere and energetic electrons like … Meet Steve, a newly discovered atmospheric phenomenon that’s so strange it still doesn’t have a formal scientific description, hence the placeholder name. The atmospheric phenomenon known as STEVE, appearing as a band of light in the sky. There was a problem. To photographers and stargazers in northern climes, Steve has been a familiar night phenomenon for decades. In a recent paper titled "The Mysterious Green Streaks Below Steve," Joshua Semeter of Boston University and a team of researchers examined yet another STEVE phenomenon not reported on before. The ‘rain’ strikes atoms, ions, and … [17], A study published in March 2018 by Elizabeth A MacDonald and other co-authors in the peer-reviewed journal Science Advances suggested that STEVE accompanies a subauroral ion drift (SAID),[18] a fast-moving stream of extremely hot particles. Sprites, UFOs, Steves and other atmospheric phenomenon that mystify. A later 2019 study determined that the STEVE’s mauve streak and green picket fence are actually a result of two distinct phenomena from two separate processes. Proper noun . [11][12], Robert Lysak, during the fall meeting of the American Geophysical Union in December 2016, suggested "Strong Thermal Emission Velocity Enhancement" as a backronym of STEVE,[13] one that has since been adopted by the team at NASA Goddard Space Flight Center studying the phenomenon. Reblogged this on Tallbloke's Talkshop and commented: Quote: ‘STEVE is a recently identified atmospheric phenomenon caused by supersonic plasma jets flowing at altitudes >100 km.’ Scientists continue to wrestle with its electromagnetic mysteries. Late at night on July 25, 2016, a thin river of purple light slashed through the skies of northern Canada in an arc that seemed to stretch hundreds of miles into space. According to analysis of satellite data from the European Space Agency's Swarm mission, STEVE is caused by a 25 km (16 mi) wide ribbon of hot plasma at an altitude of 450 km (280 mi), with a temperature of 3,000 Â°C (3,270 K; 5,430 Â°F) and flowing at a speed of 6 km/s (3.7 mi/s) (compared to 10 m/s (33 ft/s) outside the ribbon).

As Phil Darlington explains, a … Move over Boaty McBoatface – a group of aurora enthusiasts have given a newly discovered atmospheric phenomenon the name 'Steve', because ... well what else are we going to call a mysterious glowing light in the sky? An atmospheric phenomenon has been discovered by citizen scientists and aurora photographers – and so little is known about it right now that they’ve named it Steve. A bunch of citizen scientists and aurora photographers in Canada have discovered an atmospheric phenomenon that scientists know little about. STEVE's mauve streaks occur due to heated charged particles in the atmosphere, whereas the typical auroras were glowing. [22], The green emissions seem to be related to eddies in the supersonic flow of charged particles, similar to the eddies seen in a river, which move more slowly than the other water around them. The name for this new atmospheric phenomenon is known by the acronym “STEVE,” which stands for: Strong Thermal Emission Velocity Enhancement. STEVE (Strong Thermal Emission Velocity Enhancement) is an atmospheric optical phenomenon that appears as a purple and green light ribbon in the sky, named in late 2016 by aurora watchers from Alberta, Canada. As of March 2018, STEVE has only been spotted in the presence of an aurora. "STEVE is caused by a 25 km (16 mi) wide ribbon of hot plasma at an altitude of 450 km (280 mi), with a temperature of 3,000 °C (3,270 K; 5,430 °F) and flowing at a speed of 6 km/s (3.7 mi/s) (compared to 10 m/s (33 ft/s) outside the ribbon)." The aurora enthusiasts have named it Steve. [14], STEVE may be spotted closer to the equator than the aurora,[15] and as of March 2018 has been observed in the United Kingdom, Canada, Alaska, northern U.S. states, and New Zealand. Ratzlaff was referring to an atmospheric optical phenomenon that appears as reddish and green light in the sky. The name “Steve” is a nod to the 2006 animated film “Over the Hedge,” in which its characters chose “Steve” as a benign name for something unknown. Trying to decide if the unanswered question What was Steve?Is it called something else now? This amateur astronomer's photograph, taken on May 8, 2016, in Keller, Washington, was used in the new research about the celestial phenomenon called STEVE. Receive news and offers from our other brands? Researchers suspect that it may be the result of some native process in the ionosphere (50 and 600 miles (80 to 1,000 kilometers) above Earth’s surface, just below the planet’smagnetic field). For now, the mysterious atmospheric phenomenon will continue to be known as Steve, until Eric Donovan and his colleagues come up with a better name, along with an explanation, which they are working on. STEVE (Strong Thermal Emission Velocity Enhancement) is an atmospheric optical phenomenon that appears as a purple and green light ribbon in the sky, named in late 2016 by aurora watchers from Alberta, Canada. Fellow Aurora Chaser Robert Downie kneels in the foreground while photographer Ryan Sault captures the narrow ribbon of white-purple hues overhead. STEVE was not observed from October 2016 to February 2017, or from October 2017 to February 2018, leading NASA to believe that STEVE may only appear in certain seasons.
