Aurora

Researchers have found the oldest known reference to a candidate aurora in a celestial event described in an ancient Chinese text dated to around the 10th century BCE.
The space weather event, described recently in the journal Advances in Space Research, predates the previous oldest reference to auroras by some three centuries.
