NOAA's arcs: the auroral oval

Auroral Activity extrapolated from the NOAA POES satellite

The only times I can remember seeing the Aurora Borealis (I've never been south of the equator, so no chance of having seen the Aurora Australis were once near Ashland, Wisconsin, and, surprisingly (to me), once here in Colorado. Lori and I were driving along and thought there was a strange shimmer in the sky. We then saw many other cars pulled over to get a better look. We followed suit and watched the show. On the NOAA page I can wistfully look from time to time to see whether there is any chance of catching the show again without having to venture pole-wards of either 45th parallel in Winter.
