Steve?
Sometimes nicknames stick! When a strange phenomenon starts happening in the sky it needs a name right? If little is known about what it is or what is causing it sometimes a placeholder name is used until more information comes to light. For the last few years, Aurora gazers have observed and reported: “a wispy strand of purple light running across the country from east to west, sometimes flanked by neon green fingers that appear to wave.” This unique Aurora was given the nickname Steve. 
A recent research paper has shed light on what Steve actually is, and scientists have proposed a moniker: Strong Thermal Emission Velocity Enhancement - meaning, for now, the name Steve is here to stay.
