Depiction of the northern auroral oval from the Ovation site on July 15, 2013. Southern Canada and the northern fringe of the U.S. were under the oval with northern lights visible. The red âview lineâ shows how far south the aurora could be seen that night.
Â­The aurora borealis (the Northern Lights) and the aurora australis (the Southern Lights) have always fascinated mankind, and people even travel thousands of miles just to see the brilliant light shows in the earth's atmosphere.he auroras generally occur along the auroral ovals, which center on the magnetic poles (not the geographic poles) and roughly correspond with the Arctic and Antarctic circles. There are times, though, when the lights are farther south, usually when there are a lot of sunspots.
