"Steve" is back!

Less than three weeks left until astronomical spring in the Northern hemisphere. For unknown reasons shortly before or after the equinoxes in the Earth's magnetosphere begin to flow hot ribbon plasma. Ayumi Bakken saw one of them on 28 February over Fairbanks, Alaska.

""The Steve" is back! Its narrow luminous band appeared near the Big Dipper for a few minutes, and then quickly disappeared," said Bakken.

STEVE — a reduction from the Strong Thermal Emission Velocity Enhancement — has long been considered a kind of Aurora. But the auroras are the result of the interaction of cosmic particles with the earth's magnetosphere, and for the "Steve" particles are not needed. Satellite measurements show that this is a hot ribbon strip, sweeping through the upper layers of Earth's magnetic field at speeds of over 16 000 km/h.

Although "Steve" is not the Aurora, it often occurs with them. In this case, next to purple ribbon you can see the green glow of the Aurora in the side, caused by a geomagnetic storm of G1.
