Aurora borealis - December 2003

Click on the images to get the full size image. We had really good aurorae in the Isle of Man during December. I took several shots from behind my house, and then went to the Calf Sound (which is very dark at night). It was a moonless night, and the aurora lit the sky up well enough that I could see my way around whilst setting up the camera at the Calf sound. (Good job too, there are some cliffs to fall off). The aurora lasted several hours, from about 6:30pm until around 10pm and were obvious even in areas saturated by streelighting. I had seen pictures of the aurora in encyclopaedias and text books, and the photographs always showed a small red area in the sky and the rest dark. The real thing turned out to be much better - at its peak the entire sky was covered in red and green light. Looking directly up, you could see a sort of 'point of origin'. The lights shifted over time. I didn't expect the photographs to come out at all, and was very pleasantly surprised at the results - better than the pictures in the newspaper, even if I say so myself.

Note the thumbnails are a lot grainier than the full size (artifacts of gd resizing them, I suppose).

Looking from the back of my house towards Port Erin. This was just using the camera's automatic timer with a wide open shutter. Exposure was on the order of 10 seconds.
The same scene, but with a 30 second exposure and f11. Note how the stars are smudged a bit more.
Turned the camera on its side, and pointed it up a bit more for the full effect. As you can see, the aurora was very bright. It was obvious even in heavily streetlit areas. However, it was amazing how many people simply didn't even notice despite the sky being lit up like summer dusk, but in green and red!
I then went to the Calf of Man and experimented with exposure times of up to 5 minutes at f32 (which came out very over exposed). This one was a shorter exposure with a wider aperture. Since it was freezing cold, I had lost the ability to set the tripod up quite straight! The sea normally doesn't slope.
