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. 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. The celestial phenomenon known as STEVE is likely caused by a combination of heating of charged particles in the atmosphere and energetic … 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. Ratzlaff was referring to an atmospheric optical phenomenon that appears as reddish and green light in the sky. ", "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. [10] Reportage of the heretofore undescribed unusual "aurora" went viral as an example of citizen science on Aurorasaurus. Proper noun . NY 10036. © You will receive a verification email shortly. [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. The celestial phenomenon known as STEVE is likely caused by a combination of heating of charged particles in the atmosphere and energetic electrons like … Sightings of picket-fence aurora have been made without observations of 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. Turbulent eddies and whirls dump some of their energy into the green cannonballs.” This idea may explain their pure color. The aurora enthusiasts have named it Steve.It has garnered the attention of researchers at the European Space … 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. Thousands of new, high-quality pictures added every day. [Aurora Images: See Breathtaking Views of the Northern Lights], According to researchers at the University of Calgary in Canada and the University of California, Los Angeles, Steve does not contain the telltale traces of charged particles blasting through Earth's atmosphere that auroras do. But, for the sake of keeping the conversation going, she and her colleagues dubbed the mysterious force a "sky glow.". Compared to the northern lights — which tend to shimmer in broad bands of green, blue or reddish light depending on their altitude — Steve is remarkably slim, usually appearing as a single ribbon of purplish-white light. The mysterious ribbon of atmospheric light known as STEVE slashes through the sky over British Columbia, Canada, on April 10, 2018. 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. 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. Now, scientists understand that the elements of a STEVE originate from two distinct atmospheric phenomenon, writes Toshi Nishimura, a space physicist at … The beautiful atmospheric phenomenon “Steve” was first documented by a Facebook Group last year. What this ribbon lacks in girth, it makes up for in length; unlike the wavy northern lights, Steve appears to stab straight upward into the night sky, often spanning more than 600 miles (1,000 kilometers). It has garnered the attention of researchers at the European Space Agency (ESA), NASA, and other institutions. is in need of attention I checked Wikipedia's Steve (atmospheric phenomenon); Occurrence and cause which says: Occurrence and cause. Auroras tend to be a mixture of hues caused by energetic particles raining down through the upper atmosphere. Dr. Dr. Steve (atmospheric phenomenon), a humorously named atmospheric glow; Steve; See also. At about 200 miles (300 km) above Earth, the air inside Steve blazed about 5,500 degrees Fahrenheit (3,000 degrees Celsius) hotter than the air on each side, and moved about 500 times faster. She also included GPS coordinates from Vimy, Alberta, that helped Donovan link the data to identify the phenomenon. STEVE's mauve streaks occur due to heated charged particles in the atmosphere, whereas the typical auroras were glowing.

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. 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). [21] The study also showed these phenomena appear in both hemispheres simultaneously. 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. Apr. Before you assume Steve is named … Steve, therefore, is not an aurora at all, but something entirely different: a mysterious, largely unexplained phenomenon that the researchers have dubbed a "sky glow. While looking like a family member of … (Photo courtesy Vanexus Photography) Fellow Aurora Chaser Robert Downie kneels in the foreground while photographer Ryan Sault captures the narrow ribbon of white-purple hues overhead.
