APOD 1.8: Auroral Corona Over Norway

 

Auroras rarely reach below 60 kilometers off the ground, and can range up to 1000 kilometers. Auroras are made from prtons and electrons striking differeent atoms and molecules in the Earth's atmosphere. the uncommon auroral corona can happen when aurora happens directly above or is taken from directly under. This green and purple aurora exhibition occurred last month above Kvaløya, Tromsø, Norway. The Sessøyfjordenfjord runs through the foreground, while numerous stars are visible far in the distance.
