Aurora ~is~ an atmospheric phenomenon, after all

I've only managed one decent photo in all my years. And that was nearly
17 years ago...

If you want to know the possibility of seeing an aurora at your location try
this :
www.swpc.noaa.gov/SWN/index.html
and check the "Magnetic Field Bz Component" graph-when the arrow goes
strongly negative it's time to look. Other graphs will tell you how far
south the aurora might get. Thanks to George N. in a.b.p.astro for this.
