Aurorae are indeed beautiful, aren't they, Connie? We almost never get them this far south, but the one time we did ... oh! what a night!

The southern- and northern-hemisphere versions are, I believe, respectively called the aurora australis and the aurora borealis.

Connie's gallery-link is spectacular, and several incredible aurora pictures can be found on that lovely site Helen provided about a week and a half ago:

aurora over New Zealand: http://antwrp.gsfc.nasa.gov/apod/ap010406.html
volcano and aurora in Iceland: http://antwrp.gsfc.nasa.gov/apod/ap020121.html
the Black Aurora: http://antwrp.gsfc.nasa.gov/apod/ap020101.html
red aurora: http://antwrp.gsfc.nasa.gov/apod/ap020115.html (personal favorite)
aurora over clouds: http://antwrp.gsfc.nasa.gov/apod/ap010402.html
Or choose your own from http://antwrp.gsfc.nasa.gov/cgi-bin/apod/apod_search?aurora. As you can see, I'm excited about that site. Thank you, Helen!
