Aurora Borealis

The word "aurora" is derived from the name of the Roman goddess of the dawn, Aurora, who travelled from east to west announcing the coming of the sun.[4] Ancient Greek poets used the corresponding name Eos metaphorically to refer to dawn, often mentioning its play of colors across the otherwise dark sky (e.g., "rosy-fingered dawn").[5]

The words "borealis" and "australis" are derived from the names of the ancient gods of the north wind (Boreas) and the south wind (Auster) in Greek mythology.

Most auroras occur in a band known as the "auroral zone",[6] which is typically 3° to 6° (approximately 330-660 km) wide in latitude and between 10° and 20° from the geomagnetic poles at all local times (or longitudes), most clearly seen at night against a dark sky.
