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.
If you live in the high latitudes, like Alaska, or New Zealand, you've probably had a chance to see an aurora. Here in Canada, we call them the Northern Lights or the Aurora Borealis, but the lucky folks in the far southern latitudes see them too. On a good night, you can see flickering sheets of light that dance across the night sky, producing an amazing display of colors.
