Aurora over Switzerland

Aurora over Switzerland

Astrophotographer Role Bigler: "Aurora Borealis Emmentalensis. Aurora borealis over the Emmental (Switzerland). Not an everyday occurrence."

On Earth, auroras are mainly created by particles originally emitted by the Sun in the form of solar wind. When this stream of electrically charged particles gets close to our planet, it interacts with the magnetic field, which acts as a gigantic shield. While it protects Earth’s environment from solar wind particles, it can also trap a small fraction of them. Particles trapped within the magnetosphere—the region of space surrounding Earth in which charged particles are affected by its magnetic field—can be energized and then follow the magnetic field lines down to the magnetic poles. There, they interact with oxygen and nitrogen atoms in the upper layers of the atmosphere, creating the flickering, colorful lights visible in the polar regions here on Earth.

Earth auroras have different names depending on which pole they occur at. Aurora Borealis, or the northern lights, is the name given to auroras around the north pole and Aurora Australis, or the southern lights, is the name given for auroras around the south pole.

  1. Wonderful Image
    Where exactly has it been taken?
    Is this the Emme river in the front? Gruess aus Burgdorf

  2. The photographer, Role Bigler, does not provide additional location information.
    It appears to be the Emme river.
    General Information: The Emmental (English: Emme Valley) is a valley in west-central Switzerland, forming part of the canton of Bern. It is a hilly landscape comprising the basins of the rivers Emme and Ilfis.
