When does Aurora Borealis occur?

Answer 1

Aurora Borealis occurs in the northern hemisphere, and its companion, Aurora Australis in the Southern hemisphere.

Both are caused by a torrent of charged particles from our Sun, and which are directed by the earth's magnetic poles towards those poles.

This occurrence is most common during solar storms and sunspot activity, which occurs in an 11-year (or 22-yeaar) cycle.

In intense solar storms, they may even be seen as far south in the USA as Texas, but very rarely. Under these conditions, the excess of charged particles can damage electrical and telephone wiring (and Transformers), by causing large currents to flow.

Answer 2

The Aurora Borealis, also known as the Northern Lights, occurs mainly in the fall and winter months in the Northern Hemisphere when solar particles collide with gases in the Earth's atmosphere, producing colorful light displays in the sky. The peak times to see the Aurora Borealis are typically around the equinoxes in March and September and during the winter months when nights are longer and darker.
