Aurorae

Aurorae or polar lights are natural light displays in the night sky, typically in the ionosphere.  Aurorae are produced by the collision of charged particles (solar wind) from the Earth’s magnetosphere. Temporarily, when a strong magnetic storm arises, these phenomena can also be seen in temperate (northern) latitudes.
