Aurora photographers find new night sky lights and call them Steve

A group of aurora enthusiasts have found a new type of light in the night sky and named it Steve.
Eric Donovan from the University of Calgary in Canada spotted the feature in photos shared on a Facebook group.
He did not recognise it as a catalogued phenomenon and although the group were calling it a proton arc, he knew proton auroras were not visible.
Testing showed it appeared to be a hot stream of fast-flowing gas in the higher reaches of the atmosphere.
The European Space Agency (ESA) sent electric field instruments to measure it 300km above the surface of the Earth and found the temperature of the air was 3,000C hotter inside the gas stream than outside it.
