The Northern Lights

September 12, 2014 — HAPPY ANNIVERSARY GAIL!
The northern lights occur when charged particles from the sun collide with atoms of gas in Earth’s atmosphere. This display happened just after a solar maximum, in 2004. You can see Orion rising above my house in the eastern sky. The aurora was intense and easily visible even though that is a light-polluted part of my sky. As I write this, there is a better-than-even chance of a fine aurora tonight!
These were among my first ever astronomical images. Shot with an Olympus 5MP point-and-shoot camera on a tripod. Each image was 4 seconds at f/2.8. Unfortunately, not knowing any better, I saved them only as low quality jogs. Doh!
