I understand that there were Northern Lights sightings in the county last week. I missed them, but I'll be watching out for them for a while.
If the night is predicted to be clear, you can check for the location of the auroral oval on this site from the National Oceanic and Atmospheric Administration. The arrow indicates when the sun is right now; the oval sort of drifts away from the sun as the earth turns. A good night is when the yellow and orange section drifts away from the poles enough to cover your latitude.
