Maria Temming is the staff reporter for physical sciences, covering everything from chemistry to computer science and cosmology. Recently, studies of the picket fence’s color have cast doubt on its origins. 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. Whatever is going on with STEVE’s horizontal green features, “there’s some tantalizing evidence” that they’re related to the vertical picket fence, Semeter says. Courtesy of Donna Lach 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! But this pink-ish ribbon isn't an aurora — it's STEVE! The rapidity of science, technology and understanding has allowed us to learn and share this knowledge of the interactions within our atmosphere which create this distinct celestial glow much faster than ever before. STEVE, short for Strong Thermal Emission Velocity Enhancement, is a sky glow that appears south of the northern lights (SN: 3/15/18). 6 -18 years……………… 1.000,- ISK, https://www.facebook.com/aurorareykjavik/Facebook, the best places to see the Northern Lights in Iceland. 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. Where aurora activity occurs anywhere between 50 – 640 km in altitude, STEVE sits at 450 km. From 2015 to 2016, citizen scientists reported 30 instances of a purple ribbon in the sky, with a green picket fence structure underneath. 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 … Essentially, STEVE is a phenomenon caused by a combination of particle friction and waves causing energetic electrons to move from the magnetosphere to the ionosphere… no wonder it has taken this long for an answer! 99 likes. It's taught me to be proud of my body for what it can do." Particularly, with the Northern Lights, science has propelled our understanding of probabilities, causation and the technical interactions behind the solar wind and our atmosphere that have led to eons of wonder from humankind. Now named STEVE, or Strong Thermal Emission Velocity Enhancement, this phenomenon is still new to scientists, who are working to understand all its details. In fact, there is evidence that STEVE has been observed and spotted since the 18th century in 1705. The mysterious, aurora-like phenomenon called STEVE just got a little weirder. 23. Believe it or not, this phenomenon was named ‘STEVE’ initially in homage to the animated movie ‘Over the Hedge’ where the creatures are unsure of what a hedge is, and so promptly just name it ‘Steve’. There are 15 candidates who filed for the April 2021 Aurora city election, including three for mayor. STEVE is a relatively newly assessed and understood phenomenon. According to NASA, STEVE actually occurs much closer to the equator than the aurora which only occurs around the Earth’s poles. These green blobs might arise from turbulence in the torrent of plasma that creates STEVE’s purple band, Semeter says. Source: STEVE Atmospheric Phenomenon. Specifically, STEVE mainly occurs around 5-10 degrees further south in the Northern Hemisphere than the Auroral Oval. That fence looks similar enough to the shimmering green curtains seen in the aurora borealis that scientists thought at least this part of STEVE could be a type of aurora. Meet Ray! 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. Those electrons make nitrogen in the air glow blue and oxygen glow green. The weird, purple-and-green sky glow known as STEVE (shown) continues to defy explanation. 2.000,- ISK They may have been dazzled by STEVE as well. Now named STEVE, or Strong Thermal Emission Velocity Enhancement, this phenomenon is still new to scientists, who are working to understand all its details. Aurora photographers have been capturing pictures of STEVE for decades without actually understanding what it was. Grandagarður 2 It occurs as waves move from Earth’s magnetosphere to the ionosphere. With the new discovery of STEVE, we now finally have a reason to look south and enjoy evenings of photographing, discovering and learning more about the wonders of the night sky above. It was officially discovered in Alberta, Canada by our North American aurora watching friends in the Facebook group, ‘Alberta Aurora Chasers’, who named the phenomenon. The data found that STEVE is actually caused by a 25 km wide ribbon of hot plasma at an altitude of 450 km, at an average temperature of 3000 °C, and a flowing speed of 6 km/s. Steve Dalkowski was one of the fastest pitchers in organized baseball history with a fastball thought to be over 100 miles per hours. The sky glow nicknamed STEVE is a purple arc of light often accompanied by a vertical row of green stripes. 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. 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. Aurora Steve. Relatively new research indicates that the formation of STEVE occurs in two distinct parts – the mauve, pink and purple streaks and the green ‘picket fence’ aspect which is similar to an aurora. Here in Iceland, we count ourselves even more fortunate to have the ability to spend our long winter nights gazing up at the impressive Northern Lights that dance silently, yet passionately, over our heads most evenings. 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. 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. Visitation. Iceland According to NASA, STEVE actually occurs much closer to the equator than the aurora which only occurs around the Earth’s poles. AGU Advances. Somewhat bizarrely, this phenomenon is, in fact, much less rare than you would think, though it was never investigated before initial discovery in 2016. 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 is awesome, heavenly and mysterious. So, as you set up your camera and settle in for a night gazing at the stars during our winter months in Iceland, take a moment to check both north and south, try various test shots in both directions and see if you can capture both these incredible wonders of the northern skies. E-mail us at feedback@sciencenews.org. 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. From 2015 to 2016, citizen scientists reported 30 instances of a purple ribbon in the sky, with a green picket fence structure underneath. “It’s really weird, and nobody really knows what’s going on just yet,” says Joshua Semeter, an engineer at Boston University. MEMORIAL EVENTS. STEVE (the Strong Thermal Emissions Velocity Enhancement) is a spectacular and colorful celestial phenomenon that was first spotted 2016 . A new finding about the formation of streaks within the aurora-like STEVE phenomenon brings scientists one step closer to solving the mystery. Unlike the aurora, however, STEVE isn’t a dancer! Elfiehall. These are the best places to see the northern lights in 2020. A new finding about the formation of streaks within the aurora-like STEVE phenomenon brings scientists one step closer to solving the mystery. Astrophotographer Paul Zizka shared this photo of the aurora phenomenon "Steve" — then called a potential proton arc — with Space.com in October 2015. … However, since 2016, STEVE has been the term on the lips of aurora enthusiasts across the world. She has bachelor's degrees in physics and English, and a master's in science writing. For those of you who have seen a relatively weak Northern Lights display, which often can only appear as a thin pale band across the sky, STEVE is much closer to this. As is the case with astronomy, there are constantly new discoveries and observations that lead to new and exciting theories and hypotheses. There’s no doubt that for some time due to our knowledge of aurora science and our regular sightings experience that we know the best places to see the Northern Lights in Iceland. This reaction causes friction which then heats up the particles, resulting in the mauve and pinkish glow (incandescent lightbulbs work in a similar way) that causes the main obvious streaks of the STEVE phenomenon. Aurora-chasing citizen scientists help discover a new feature of STEVE Date: November 13, 2020 Source: NASA/Goddard Space Flight Center Summary: A … Aurora-watchers gazing at spectacular displays over the Labor Day weekend may have been seeing more than the northern lights. Stabbing Suspect Steve Sinclair, Who Yelled ‘Black Lives Matter,’ Charged With Hate Crime August 27, 2020 at 8:46 pm Filed Under: Aurora News , Aurora Police , Steve Sinclair 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. Only in the past few years have scientists found an explanation for this strange celestial phenomenon. J. Semeter et al / AGU Advances 2020 Whereas, the green ‘picket fence’ aspect of STEVE develops from a completely different reaction. Steve's Club National Program . Written By: Bob King for the Duluth News Tribune | Dec 1st 2020 - 6pm. This region is where the waves can both energise electrons and move them out of the magnetosphere, which create this similar aurora style appearance. In 2018, a new aurora-like discovery struck the world. Shortly after this, it was then investigated by analysis from the satellite data of the European Space Agency’s Swarm mission. “We found events where these little feet appear before or at the same time as the green column above it.” And some horizontal and vertical streaks looked connected. 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. Wikimedia. In 2018, a new aurora-like discovery struck the world. Now named STEVE, or Strong Thermal Emission Velocity Enhancement, this phenomenon is still new to scientists, who are working to understand all its details. But, with new observations in our skies above, STEVE now adds a new element and anticipation to the upcoming winter hunts. While the green streaks do contain glowing oxygen, a lack of nitrogen emissions suggest that it is not the same as an aurora. This is not to say it’s any less special than the Northern Lights. 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. Fast-forward to 2020, and scientists are now questioning the results of this research. 101 Reykjavík​ 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. 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. Auroras form when electrons from the magnetic bubble, or magnetosphere, surrounding Earth cascade into the atmosphere (SN: 2/7/20). However, when it comes to the more recent question from our travellers of how to spot STEVE, we’re still playing catch up with sourcing the right answers. A meteor streaks overhead as a Strong Thermal Emission Velocity Enhancement (STEVE) dances near the aurora and Comet Neowise hangs over Manitoba, Canada, July 14, 2020. Here is Steve Wishart’s obituary. ...

Tel: +354 780-4500 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. 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. Computer simulations of plasma flowing through the atmosphere could test whether the idea is correct. “It appears that the green emission is actually expanding upward along the magnetic field line,” Semeter says. You can send your sympathy in the guestbook provided and share it with the family. As a result, those high-energy electrons may get tangled up in small vortices on the edge of the plasma stream, below the purple streak. Sorry, your blog cannot share posts by e-mail. 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. Positively charged atoms in the plasma may rush through the atmosphere largely unimpeded, forming a smooth purple arc.
