When does the Antarctic light usually appear?

The Antarctic light usually occurs at night in the polar regions, and the winter when it enters the southern hemisphere is the time when the Antarctic light bursts: from May to August, the best place to see the aurora in the southern hemisphere must be Tasmania at the southern tip of Australia.

The most common place where Antarctic light appears is the annular belt near the south magnetic dimension of 67 degrees, which is called the Antarctic light belt. Aurora activity occurs almost every day in the aurora area. The shape of aurora is sometimes stable, sometimes it changes continuously, and it is generally strip, arc, curtain or emission.

The reasons for the formation of Antarctic light:

The sun is a huge and hot gas ball, and the nuclear reactions of various chemical elements are carried out inside and on its surface, resulting in a powerful stream of charged particles, which are emitted from the sun and shot into the surrounding space at a very high speed.

When this charged particle stream shoots into the thin upper atmosphere around the earth, it is attracted to the poles by the earth's magnetic field and collides violently with the molecules of the thin gas, thus producing a luminous phenomenon, which is aurora.
