STEVE marks the first observed visual effect accompanying a SAID. (Photo courtesy Vanexus Photography) ", "Our main conclusion is that STEVE is not an aurora," lead study author Bea Gallardo-Lacourt, a space physicist at the University of Calgary in Alberta, Canada, said in a statement. Visit our corporate site. 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. Auroras tend to be a mixture of hues caused by energetic particles raining down through the upper atmosphere. Source. Please deactivate your ad blocker in order to see our subscription offer. For a while, STEVE's origins were elusive. Photo: Elfiehall via Wikimedia Commons, CC-BY-SA 4.0 In July of last year, there was a thin trail of purple light that was witnessed streaking across the sky in northern Canada. For their new study, the team combined images taken by a network of ground-based cameras with data collected from one of the National Oceanic and Atmospheric Administration's Polar-orbiting Operational Environmental Satellites, which were equipped with instruments capable of detecting charged particles descending through Earth's atmosphere. [5] However, the first accurate determination of what STEVE is was not made until after members of a Facebook group called Alberta Aurora Chasers named it, attributed it to a proton aurora, and called it a "proton arc". New York, (Image: © Ryan Sault / Alberta Aurora Chasers). The ‘rain’ strikes atoms, ions, and … 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. The celestial phenomenon known as STEVE is likely caused by a combination of heating of charged particles in the atmosphere and energetic … [1], One of the aurora watchers, photographer Chris Ratzlaff,[8][9] suggested the name "STEVE" from Over the Hedge, an animated comedy movie from 2006, in which its characters chose that as a benign name for something unknown. Thousands of new, high-quality pictures added every day. 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. [16] STEVE appears as a very narrow arc extending for hundreds or thousands of miles, aligned eastâwest. In late 2016, the backronym "Strong Thermal Emission Velocity Enhancement" was adopted. 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. [7] He correlated the time and location of the phenomenon with Swarm satellite data and one of the Alberta Aurora Chasers' photographers, Song Despins, whose photos are not shown on this page. 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. The Alberta Aurora Chasers Facebook group shares pictures its members take of the Northern Lights. 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. Sightings of picket-fence aurora have been made without observations of STEVE. Known by the acronym STEVE, it's 280 miles above Earth. Newly-Observed Atmospheric Phenomenon Named "Steve" Miss Cellania • Tuesday, April 25, 2017 at 12:00 AM. Ratzlaff was referring to an atmospheric optical phenomenon that appears as reddish and green light in the sky. Several distinct layers make up Earth's atmosphere, including the mesosphere, which starts 31 miles (50 km) up, and the thermosphere, which starts at 53 miles (85 km) up. This Steve event was photographed May 8, 2016, at Porteau Cove Provincial Park in British Columbia. Now, scientists understand that the elements of a STEVE originate from two distinct atmospheric phenomenon, writes Toshi Nishimura, a space physicist at … While looking like a family member of … Ratzlaff was referring to an atmospheric optical phenomenon that appears as reddish and green light in the sky. "So right now, we know very little about it. Steve is definitely created in the ionosphere, Nishimura’s team reports, but the purple slither doesn’t appear to be an aurora, which is defined as light emissions caused by energetic electrons. [10] Reportage of the heretofore undescribed unusual "aurora" went viral as an example of citizen science on Aurorasaurus. [4], STEVE often, although not always, is observed above a green, "picket-fence" aurora. Amateur Skywatchers Spot New Atmospheric Phenomenon Its name is Steve, and it’s more common than you might think. 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. © Steve (atmospheric phenomenon), a humorously named atmospheric glow; Steve; See also. What could that something be? Alberta Aurora Chasers capture STEVE, the new-to-science upper atmospheric phenomenon, on the evening of April 10, 2018 in Prince George, British Columbia, Canada. The aurora enthusiasts have named it Steve. To photographers and stargazers in northern climes, Steve has been a familiar night phenomenon for decades. [1][2][3] In August 2018, researchers determined that the phenomenon's skyglow was not associated with particle precipitation (electrons or ions) and, as a result, could be generated in the ionosphere. 24 APRIL 2017. 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. On March 28, 2018, Steve again appeared in the skies of northern Canada and happened to fall within the sight of both ground- and sky-based recording equipment. Alberta Aurora Chasers capture STEVE, the new-to-science upper atmospheric phenomenon, on the evening of April 10, 2018 in Prince George, British Columbia, Canada.

A New Atmospheric Phenomenon Called Steve Kaushik Patowary Jun 12, 2017 0 comments For the past three years, members of a Facebook group called the Alberta Aurora Chasers , consisting of photographers who exchange tips and images of the famed northern lights, have been capturing images of a gorgeous arc of light across the sky. Receive mail from us on behalf of our trusted partners or sponsors? ", Given its coincidence with the northern lights, Steve was just thought to be part of the aurora — the shimmering sheets of nighttime color that appear in the sky when charged plasma particles streak out of the sun, sail across space on solar winds and jolt down Earth's magnetic field toward the planet's poles. 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. Dr. Dr. The ionosphere consists of three sections within the mesosphere and thermosphere, labeled the D, E and F layers, according to the UCAR Center for Science Education. The name for this new atmospheric phenomenon is known by the acronym “STEVE,” which stands for: Strong Thermal Emission Velocity Enhancement.
