It is not fully understood either and there has been some discussion to call it STEVE [ an acronym meaning “Strong Thermal Emission Velocity Enhancement”] It was not observed from October 2016 to February 2017. STEVE (strong thermal emission velocity enhancement) STEVE is a newly discovered optical emission in the upper atmosphere, and has become one of the hottest topics in auroral researches. Scientists tend to classify optical features in the sky into two categories: airglow and aurora. We discuss optical phenomena in the subauroral region, summarize observational results, present conclusions about their origin, and pose a number of open questions that warrant further investigation of proton aurora, detached subauroral arcs and spots, stable auroral red (SAR) arcs, and STEVE (Strong Thermal Emission Velocity Enhancement). You can be assured our editors closely monitor every feedback sent and will take appropriate actions. Glowing in mostly purple and green colors, a new type of Aurora is sparking the interest of scientists, photographers & astronauts. It is Strong Thermal Emission Velocity Enhancement.

However, once you understand how these auroras form it makes mores sense. "I'm not entirely sure about anything with respect to this phenomenon just yet," Joshua Semeter, a professor at Boston University and first author on the paper, said. This narrow, subauroral, visible structure, distinct from the traditional auroral oval, was largely undocumented in the scientific literature and little was known about its formation. What they do know is that STEVE is not a normal aurora—some think maybe it's not an aurora at all—and a new finding about the formation of streaks within the structure brings scientists one step closer to solving the mystery. New science in plain sight: Citizen scientists lead to the discovery of optical structure in the upper atmosphere, Scientists have now learned, despite its ordinary name, that Steve may be an extraordinary puzzle piece in painting a better picture of how Earth’s magnetic fields function and interact with charged particles in space ….

We investigate its origin in space through spacecraft and remote sensing techniques. By 2016, Steve was brought to the attention of scientists, who turned the name into a backronym for Strong Thermal Emission Velocity Enhancement. The Swarm satellite recorded information on the charged particles’ speeds and temperatures, but does not have an imager aboard. Steve consistently appears in the presence of auroras, which usually occur at a higher latitude area called the auroral zone. Zeller has been involved with the discovery of STEVE from the start. They suggest the streaks could be moving points of light—elongated in the images due to blur from the cameras. By 2016, Steve was brought to the attention of scientists, who turned the name into a backronym for Strong Thermal Emission Velocity Enhancement. Strong Thermal Emission Velocity Enhancement. Semeter said. "Citizen scientists don't get into the patterns that scientists get into. These features are formed differently but also look different—airglow can occur across Earth, while auroras form in a broad ring around Earth's magnetic poles. The phenomenon does now have a backronym of an official name: strong thermal emission velocity enhancement (Steve for short). strong thermal emission velocity enhancement. The name stuck, though researchers now know it by the more-official sounding STEVE, short for Strong Thermal Emission Velocity Enhancement.
