I have the feeling you want to know this because of the Japan earthquake, am I correct?
Im from Finland and we have been taught that they occur only above the arctic circle, and still they are quite rare. I can't be sure though, I dont know what to believe any more...
Both aurora appear around the polar regions. The Aurora Australis appears around Antacrtica and the Aurora Borealis appears around the Arctic.
The astronomical phenomenon, aurora borealis as they appear in motion, move very slowly, like watching a gentle breeze blow on a curtain.
I don't will ever appear in the U.S. It only happens once a year in Alaska.
The Aurora Borealis
''Aurora'' means Dawn and ''Borealis'' means North. So basically Aurora borealis means ''Dawn of north''.
Aurora Borealis - album - was created on 2004-06-22.
"The Northern Lights" is Aurora Borealis's commonly used name.
When the Aurora Borealis happen, they can be seen from the Aleutian Islands.

Aurora Borealis occurs in northern parts of the world. Aurora Australis in southern parts of the world. Borealis is more known because there are more places and people to see them.
Aurora boreal, or even more technical, you can also say it as in Latin "Aurora borealis"[au̯.ˈɾo.ɾa.βo.ɾeˈa.lis]
The aurora borealis occur at times of heightened states of solar activity, this also applies to the aurora australius.
