The evening of September 27 a resident of Estonia Tarmo Tanilsoo went outside hoping to see the Northern lights, however, witnessed several other atmospheric phenomena.
"I think, perhaps, I first saw the so-called phenomenon STEVE says, Tanilsoo, made also a picture of what was happening in the sky above the village Lagoya near Tartu. In the North-Western part of the sky I noticed a ribbon-like glow that seemed to crawl towards the horizon until it finally disappeared."
STEVE (Strong Thermal Emission Velocity Enhancement) is a physical phenomenon really is visually very reminiscent of the Aurora. It is caused by flows of hot gas (temperature is about 3000 ° C), overcoming the Earth's magnetosphere with a speed over 6 km/s. Similar to the "tape" occur during geomagnetic storms and the different soft purple-purple glow.
Prior to that, a powerful stream of solar wind overtook our planet on August 31, and then STEVE watched in Northern States and in Canada.
