All rights reserved. This is the name of a stunning phenomenon, a purple arch soaring high in the night sky that looks like an aurora, but is not.It was discovered by amateur If so, that could explain why STEVE’s picket fence doesn’t have quite the same color as typical auroras. While the green streaks do contain glowing oxygen, a lack of nitrogen emissions suggest that it is not the same as an aurora. When it comes to spotting STEVE, based on our observations and data this usually occurs in a southward direction when you’re in Iceland due to the location of this phenomenon at 5-10 degrees lower in latitude. APR. There are 15 candidates who filed for the April 2021 Aurora city election, including three for mayor. Published in Aurora Beacon News on Apr. Somewhat bizarrely, this phenomenon is, in fact, much less rare than you would think, though it was never investigated before initial discovery in 2016. Semeter and colleagues examined horizontal streaks below picket fences in high-resolution images of STEVE taken by citizen scientists. You can send your sympathy in the guestbook provided and share it with the family. STEVE, short for Strong Thermal Emission Velocity Enhancement, is a sky glow that appears south of the northern lights (SN: 3/15/18). While these observations do hint that the fence may arise from STEVE-specific particle interactions, it’s hard to be sure based only on photographs from the ground, says Toshi Nishimura, a space physicist at Boston University who was not involved in the work. In 2018, a new aurora-like discovery struck the world. This means the phenomenon can be seen at latitudes similar to Calgary in Canada, the UK, Alaska, northern US states as well as New Zealand in the southern hemisphere. We are sad to announce that on October 30, 2020 we had to say goodbye to Steve Wishart of Aurora, Nebraska, born in Superior, Nebraska. Published in Aurora Beacon News on Apr. Unlike the aurora, however, STEVE isn’t a dancer! Know what Dona Lach who shared the pics has to say. Courtesy of Donna Lach Wikimedia. J. Semeter et al. A combination of data and photography footage helped formulate the consensus that energetic electrons were pouring into the Earth’s ionosphere, the layer of our planet’s atmosphere where atoms lose their electrons due to solar and cosmic radiation. 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 plasmaat 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 … In fact, there is evidence that STEVE has been observed and spotted since the 18th century in 1705. Science News was founded in 1921 as an independent, nonprofit source of accurate information on the latest news of science, medicine and technology. In English, you’ll want to look directly up if you’re at an altitude 5-10 degrees below the auroral oval when it’s dark and you have clear skies, or slightly south if you’re like us and live in more northerly latitudes like Iceland. ... Getting Help from Steve and the Stedman Solutions Team. There’s a reason people have gazed up in awe at the heavens on a winter’s eve in locations in the far north for generations, you never truly know what you’re going to see! July 16, 2020 at 8:21 pm Filed Under: Aurora News , Campaign 2020 , Colorado News , Jason Crow , Steve House (CBS4) — Republicans are hoping to take back Colorado’s Congressional District 6. Specifically, STEVE mainly occurs around 5-10 degrees further south in the Northern Hemisphere than the Auroral Oval. A new finding about the formation of streaks within the aurora-like STEVE phenomenon brings scientists one step closer to solving the mystery. From 2015 to 2016, citizen scientists reported 30 instances of a purple ribbon in the sky, with a green picket fence structure underneath. Originally published for Science World on June 16, 2017 For many, the name Aurora Borealis conjures images of a cathedral of light in the sky; a shimmering, swaying, ethereal dance among the stars. Meanwhile, electrons in the plasma are far lighter and more liable to get tripped up by Earth’s magnetic field lines — giving those particles a much bumpier ride through the air. Only in the past few years have scientists found an explanation for this strange celestial phenomenon. Steve is awesome, heavenly and mysterious. Where aurora activity occurs anywhere between 50 – 640 km in altitude, STEVE sits at 450 km. It’s part of the joy of spending time under the night sky in winter in Iceland that we frequently discover and ponder over new phenomena, and share these discoveries with the world. 20, 2020. E-mail us at feedback@sciencenews.org. Elfiehall. Much like the aurora, the colours you will see with naked eye seem to vary based on levels of intensity, but a long exposure on your camera should pick up mauves, purples and greens similarly to the aurora. 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. In this blog, I’ll explain what STEVE is, our present day understandings of the phenomenon and how you can increase your chances of spotting it. Recently, studies of the picket fence’s color have cast doubt on its origins. As opposed to a red, green, or yellow aurora with a wispy, curtain-like shape , STEVE appears as a ribbon across the sky in a mauve or purplish color. This is not to say it’s any less special than the Northern Lights. “It’s really weird, and nobody really knows what’s going on just yet,” says Joshua Semeter, an engineer at Boston University. The structure of these horizontal streaks cannot be formed by the electron showers responsible for auroras, researchers report in the December AGU Advances. Now, researchers and citizen scientists have identified an even more unusual aspect of STEVE’s picket fence: small green streaks that stick out like feet from the bottom of some of its vertical stripes. “It appears that the green emission is actually expanding upward along the magnetic field line,” Semeter says. Questions or comments on this article? In simplicity, STEVE is an atmospheric optical phenomenon that appears as a purple, pink, mauve and green light ribbon in the sky, similar in aspect to the aurora. Steve Dalkowski was one of the fastest pitchers in organized baseball history with a fastball thought to be over 100 miles per hours. But, with new observations in our skies above, STEVE now adds a new element and anticipation to the upcoming winter hunts. Sorry, your blog cannot share posts by e-mail. And hopefully now, thanks to a group of citizen scientists, so will the name Steve. Meet Ray! Specifically, new research has shown that the green picket fence is not an aurora after all. 24, 2020. The mysterious, aurora-like phenomenon called STEVE just got a little weirder. In 2018, a new aurora-like discovery struck the world. You’re not going to get big intense all-sky encompassing auroral type displays with STEVE, but instead a more subtler band of glowing light. The discovery of horizontal green streaks below those stripes (one shown in the boxes) suggests that STEVE’s green features are not a kind of aurora. STEVE’s main feature is a mauve band of light formed by a stream of plasma flowing westward through the atmosphere — a different phenomenon from the one that gives rise to auroras (SN: 4/30/19). Whether it’s on a Northern Lights tour, a winter package or an Iceland self-drive adventure on your own, you’re sure to spot a cosmic light show unique to that specific evening that none will have seen before, nor see again. Please accept Echovita’s sincere condolences. Aurora-watchers gazing at spectacular displays over the Labor Day weekend may have been seeing more than the northern lights. Steve's Club National Program . However, since 2016, STEVE has been the term on the lips of aurora enthusiasts across the world. Future satellite observations could confirm whether electrons from the magnetosphere are pouring into the atmosphere in the region of a STEVE picket fence, he says. The atmospheric light show nicknamed STEVE may be even weirder than skywatchers thought. The analysis suggested that the streaks in these images were not actually lines extended across the sky, but only appeared that way due to motion blur, as spherical blobs of glowing gas moved through the atmosphere. 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. It occurs as waves move from Earth’s magnetosphere to the ionosphere. According to NASA, STEVE actually occurs much closer to the equator than the aurora which only occurs around the Earth’s poles. Here in Iceland, we’re blessed by both our position within the auroral zone and our relatively mild climate, to be considered the optimal location to watch the great celestial dances of the Northern Lights. From 2015 to 2016, citizen scientists reported 30 instances of a purple ribbon in the sky, with a green picket fence structure underneath. Now named STEVE, or Strong Thermal Emission Velocity Enhancement, this phenomenon is still new to scientists, who are working to understand all its details. 1, December 2020. doi: 10.1029/2020AV000183. Now named STEVE, or Strong Thermal Emission Velocity Enhancement, this phenomenon is still new to scientists, who are working to understand all its details. AGU Advances. Vol. For now, this is just a theory for what might be occurring. Fast-forward to 2020, and scientists are now questioning the results of this research.
