Most auroras occur between 90 and 130 km above sea level. The Northern and Southern Lights dance simultaneously and are almost mirror images of each other.

The way the aurora works is a lot like a neon sign, except that in the aurora, the conducting gas is in the upper layer of the atmosphere, instead of a glass tube, and the current circulates along magnetic field lines instead of copper wires.

This display was slow-paced.
