"Northern" light

Auroras sometimes called the northern and southern (polar) lights or aurorae are natural beautiful light displays in the sky, usually observed at night, particularly in the polar regions. They typically occur in the ionosphere. The Cree people call this phenomenon the Dance of the Spirits. It's southern counterpart, the aurora australis or the southern polar lights, has similar properties, but is only visible from high southern latitudes in Antarctica, South America, or Australasia.
