The auroras are the result of collisions between gaseous particles in the Earth’s atmosphere with charged particles released from the sun’s atmosphere. The type of gas particles affect the color of the dancing light. The most common auroral display is a shade of pale green produced by oxygen molecules 60 miles above the earth.
This surreal light display can be seen in the northern or southern hemisphere in the “auroral oval” centred over each magnetic pole. Southern auroras are not often seen as they are concentrated in a ring around Antarctica and the southern Indian Ocean.
