A mysterious glowing band was photographed in the sky over Canada

A rare atmospheric phenomenon STEVE was recorded in Canada. This is reported by Live Science.

The frame was taken by photographer Alan Dyer in Alberta through a fisheye lens (fisheye). According to eyewitnesses, the green and purple stripes were visible for 40 minutes. The STEVE phenomenon was discovered in 2017 by Canadian amateur astronomers. At first, these bands were mistaken for proton auroras, but later scientists said that proton arcs should be invisible to the human eye. In the end, with the help of the Swarm satellite, specialists managed to analyze the phenomenon, which showed that people observed a strip of hot gas with a temperature of up to 3000 degrees Celsius at an altitude of about 300 km.

According to experts, this heat is caused by the collision of charged particles in the atmosphere during geomagnetic storms. However, scientists still do not have an exhaustive explanation, as well as the ability to predict the appearance of such bands. Many additional observations and studies are required to solve the problem.
