Often a river of hot gasoline flows over your head. In this case the river created a Stable Thermal Emission Velocity Enhancement (STEVE) that glowed intellectual red, white, and crimson. Limited print of how STEVEs work live a subject of research, but contemporary evidence holds that their glow results from a swiftly-titillating river of hot ions flowing over a hundred kilometers up in the Earth’s atmosphere: the ionosphere. The extra mammoth boring red glow would possibly per chance perhaps per chance very effectively be related to the flowing STEVE, but alternatively would possibly per chance perhaps per chance very effectively be a Stable Auroral Crimson (SAR) arc, a extra unusual warmth-related glow. The featured picture, taken earlier this month in Côte d’Opale, France, is a wide-angle digital composite made because the STEVE arc formed practically overhead. Even supposing the apparition lasted easiest a handy guide a rough time, this used to be long adequate for the quickly-contemplating astrophotographer to catch in the image — can you scrutinize him?
