Cool Northern Lights Display

I just got back from observing the Northern Lights from a dark dirt road near Bowling Green, OH. It was impressive in the fact that it's been a year since the last really good display.

I observed curtains of light and rays. Colors were mostly green, with a little bit of pink (red) towards the top of the display. Activity extended from maybe 10 degrees above the northern horizon up through Cassiopea.

Even now, as I return home and am surrounded by city lights, I can make out a difuse green glow in the northern sky. It's a breathtaking sight if you've never seen it before.
