Aurora is one of a natural phenomenon

A natural phenomenon is a non-artificial event in the physical sense, and therefore not produced by humans, although it may affect humans (e.g. bacteria, aging, natural disasters, death.) Common examples of natural phenomena include volcanic eruptions, weather, and decay. Most natural phenomena, such as rain, are relatively harmless so far as humans are concerned.

There are various types of natural phenomena, which include (and are not limited to), Meteorlogical phenomena, weather, including hurricanes, thunderstorms and tornadoes, and geological phenomena , including volcanic activity and earthquakes.
