This is really fascinating. The pictures are incredible. It must be a really beautiful thing to witness - especially the green pillars.

Best wishes, Jeff.

What seems surprising Jeff is that the phenomenon is a recent discovery. Maybe researchers mistook it for aurora. Superficially, it does bear a resemblance to auroral displays.

Yes, it’s easy to see why STEVE might be confused with auroral displays. I love the description of the purple glow being caused by “hot (3000 degrees C) rivers of gas flowing through the Earth’s magnetosphere faster than 13,000 miles per hour”. It’s quite mind boggling to try and imagine.

Best wishes, Jeff.

When originally discovered this was called a 'Proton Arc' but it was pointed out that Proton Arcs are invisible in normal images. They discovers renamed it STEVE from Over the Hedge, an animated comedy movie from 2006, in which its characters chose that as a benign name for something unknown.

A backronym "Strong Thermal Emission Velocity Enhancement" has been created for STEVE.

By luck the SWARM satellite passed through the jet which provided lots of information on the speed & temperature.

STEVE has been observed from the UK so it is worth looking for it and hopefully imaging it on clear nights.

If you observe it post your images on the forum.
