Aurora Borealis, Northern Lights 1. A band of Aurora Borealis, Northern Lights, stretches over the Chugach Range near Palmer, Alaska in this February file photo. Scientists think they have discovered the energy source of the spectacular color displays seen in the northern lights. (AP Photo/Bob Martinson, FILE) 2. Northern lights dance across the sky near Palmer, Alaska, Wednesday, Nov. 22, 2006. (AP Photo/Bob Martinson) 3. The northern lights dance across the night sky over the Talkeetna Mountains near Wasilla, Alaska, Wednesday Oct. 9, 1997. The northern lights are thought to be caused by high-speed particles from the sun colliding with air molecules and are most frequent at the time of the summer and winter equinox and great sunspot activity.

Forecasters from the University of Alaska's Geophysical Institute are predicting several days of very high aurora activity this weekend with displays that could reach as far as Salem, Ore., and Chicago, Ill.

The northern lights dance Feb. 29, 2008 over the Spitsbergen Hotel in Longyearbyen, Norway on the Arctic archipelago of Svalbard, as far north as you can fly on a scheduled flight. At about 78 degrees north latitude, it is less than 1,000 kilometers (620 miles) from the North Pole. (AP Photo/John McConnico) 7. The aurora borealis, or northern lights, dance over the town of Longyearbyen, Norway Thursday Feb. 28, 2008. The phenomenon is caused by an interaction between the earth's electromagnetic field and particles emitted from the sun. (AP Photo/John McConnico) 8.

In this Sept. 3, 2006 file photo, a spectator watches the aurora borealis rise above the Alaska Range, in Denali National Park, Alaska. On Thursday, July24, 2008, NASA released findings that indicate magnetic explosions about one-third of the way to the moon cause the northern lights, or aurora borealis, to burst in spectacular shapes and colors, and dance across the sky.

Aurora occurs in both magnetic poles of the earth.
Therefore, it occurs in the southern hemisphere too especially over the Antarctica.
This is called Aurora Australis (Southern Lights) compared to Aurora Borealis (Northern Lights).
austral: pertaining to southern hemisphere
boreal: pertaining to northern area of the northern hemisphere.
