First aurora that I have been able to photograph in over a year. Three pictures merged, taken with a Canon XT, 20sec f5.6 18mm ISO1600. Included is a reading from my magnetometer.

I missed the show when the Bz was fairly far south, but even so I could still faintly see and image the aurora display. Would have been nice to get a better display with the low fog forming in the fields. Then as the sun rose there was a great ashfall display with several pink rays. Seems a bit nuts being this far south and getting noctilucent clouds here and now auroras too, in one week, along with the ashfall shows. Still going to kick myself for not being out an hour or so sooner for the better auroras, even if those weren't crazy or anything. I could only see the light from them to know they were there. Then used F1.8 with higher ISOs and longer shutters to try and image what was there.

On my final trip outside to check for noctilucent clouds, I was surprised to see a nice auroral arc hanging over the mountains to the north of my house. The display was calm, but got extremely pretty in breakup phase. What a week it's been! (Nikon D300, f/2.8, ISO800, 20 s and a few variations thereof).

These two pictures of last nights (July 21) aurora were taken at 11:38 and 11:42 PM MDT. They were both 15 second exposures set to ISO 400 at f/2.0 on a Canon Powershot G2 digital camera. No alterations or enhancements were made to the photos. I was in a park with my telescope getting ready to photograph Jupiter when I noticed a slight white patch on the horizon. At first I thought it was just some high clouds, but I checked the latest infrared satellite on my BlackBerry and there were no clouds to the north whatsoever. That's when I knew they must be the northern lights. So I changed my plans, packed up my telescope, drove to some darker skies - and got some pictures. With the naked eye they appeared mostly white, with only the slightest hint of green. But in long exposures the color really came out.
