Anyone else in the colder regions of the world get to see the northern lights tonight? I'm in northern NY (Potsdam), and they were more spectacular than usual. I hear they will be visible tomorrow night as well, with the same above-average intensity, so check em out.

If you get a chance during one of these events, check out your AM radio band. More often than not, you won't have a lot of signal from areas even to and north of you, and there will be a lot of Spanish on the dial.
Sometimes there will be a great deal of random atmospheric noise that'll drown this effect out, but you will probably hear Mexico on AM 900, AM 540 and/or AM 730 among others...
Cuba will be heard on AM 600 and probably AM 640.
I have a nice cassette recording of twenty years ago during an "auroral" session of a station called "La Voz de Victoria" from Colombia on AM 1140. I heard this loud, clear and alone on a portable radio near Champaign IL.

Clear nights between 11PM and 3AM, or so says my old Meteorology book. Haze, fog, moonlight, and ambient light will all obscure the Northern Lights. It's very low in the sky at my latitude (State College, PA), but we see it often.
For information on conditions, click here (sec.noaa.gov). If I'm remembering correctly, you want the Bz line to be at -10 for about an hour or so, the density to be less than 10, and the speed to be at or over 500. This data is taken way out in space, so that means that the Northern lights are still some minutes away. It's a realtime graph, so it's a pretty good guide.
Also, for Canadians, my old Meteorology bookmarks sent me to this site (spaceweather.gc.ca). I don't think that it's realtime, but if the graphs are going crazy, then there's a good chance you'll see the Northern Lights.
I knew keeping all of my old coursework would come in handy one day (ha!). I'm a big science geek, yes.
