This is 40 still frames from my EOS50D, taken the evening of the onset of the April 3-4-5-6 geomagnetic storm, all from the same point and with the same camera settings. I used Canon’s 50mm ƒ/1.4 lens, wide open, after manually focusing it on a star. All these shots were taken at ISO 3200, 4 seconds exposure, then combined using the Mac’s movie software and converted from .dv to .mp4 using Handbrake, and from thence to flickr.

One of the many benefits of living in the northern part of Montana is that from time to time, when the k-index reaches 5 or more, the aurora may extend far enough south for us to see it, and in my case, photograph it. Last night I had the pleasure of shooting over 300 photos of the aurora as it waxed and waned as part of the current intense geomagnetic storm. Here is one of my favorites:
