STEVE - aurora appears for the first time with light purple

Amateur scientists have recorded images of a newly discovered aurora band.

Meet STEVE, a newly discovered aurora with striking purple and blue bands!

This feature of northern light, recently recorded and recently named by Canadian amateur scientists, now has a scientific explanation. According to the Science Advance article by physicist Elizabeth MacDonald and colleagues on March 14, the color band that appears south of this main aurora is probably a tangible version of a common invisible invisible process. refers to the drift of charged or ionic particles.

According to MacDonald, NASA's Goddard Space Flight Center in Greenbeld, Md, and colleagues, measurements from terrestrial cameras and a satellite fly over when STEVE is brightest to show the transmitter range light binds to a strong ion stream in the upper atmosphere. But researchers have not been able to tell how light is coming from this flow.

STEVE Aurora.

Part of the project called Aurorasaurus , the original amateur scientists aliased this phenomenon before learning about the relationship between it and ion drift. MacDonald and his co-workers kept the name, but added an explanation: 'Strengthening Strong Heat Emissions'.

Let's just call STEVE.
