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.
People generally know the aurora borealis by their common name, the Northern Lights. The northern lights are natural phenomena that occur in nature. Often on a clear, dark night in the boreal forest, green, purple, pink, and white lights dance on the horizon changing their shape and color. It is perhaps one of natureâ¢s most fascinating displays of artistry. Specifically, the aurora borealis is Latin for ï¬northern dawn.ï¬ The aurora australis is the same phemonena in the southern hemisphere, most visible from Antarctica, Australia, and New Zealand.
