Aurora Borealis: Northen Lights

Anyone lucky enough to be in this tent is underneath an aurora borealis, also known as the northern lights. An aurora is a natural light display in the Earth's sky, predominantly seen in the high-latitude regions (around the Arctic and Antarctic).

Auroras are the result of disturbances in the magnetosphere caused by solar wind. These disturbances are sometimes strong enough to alter the trajectories of charged particles in both solar wind and magnetospheric plasma. These particles, mainly electrons and protons, precipitate into the upper atmosphere.

The resulting ionization and excitation of atmospheric constituents emit light of varying color and complexity.
