Summary: Two big sunspots emerged in mid-July, active regions 649 and 652. On July 16-17th a CME from sunspot 649 delivered a glancing blow to Earth's magnetic field and sparked Northern Lights, briefly, as far south as Michigan in the United States. On July 22nd a CME from sunspot 652 triggered a similar display. See also the May-June 2004 aurora gallery.

I struck paydirt once again with the automated robotic Aurora Cam we built, we had three frames with a deep red aurora on the northern horizon, just under the bowl of the dipper. This was a photographic aurora for us, none was seen visually for certain. We used a 16mm zenitar fisheye lens at f/3.5 and Supra 400 film for a 10 minute exposure. The rest of the frames had the aurora fading, and after about 30 minutes, it was gone.

The camera picked up a bit of purple in one image. For the most part, they were a bit faint green and sometimes red but still put on a good show. Photo details: Sony Cybershot DSC-4717 digital camera, 200 ASA, f2.0, 30s exposure.

I was out at Baker Lake for 2 hours watching the lights. The display was nearly colorless [to the human eye, but the camera picked up the colors shown here], with rays extending 40 degrees in elevation at the peak of the display (12:40am-1am Pacific Daylight Time). Canon Digital Rebel, 30 to 40 second exposures, 18mm f3.5 lens.

They started right at dark and I watched 'til midnight, but my husband got up from 2-3:00 am. and said it was still going strong. We had purple rays and green curtains with visible movement. Canon 10D, 20mm lens, 20 sec. I took one with the setting crescent moon. Another highlight about 10:20 was a great, greenish fireball going south to north which burst into smaller, orange pieces and lit up the whole ground. Sorry no picture.

Taken somewhat by surprise I didn't bother trying to be artistic, just tried to capture the moment. Having taken the image shortly after sunset, the exposure was a bit tricky. With the drought on Auroras lately it seems I've gotten a bit out of practice. Kodak 200 asa film, f2.8 @ 10 seconds

The Auroras lasted about 4 hours or so as a diffuse glow. There were about 3 or 4 short periods where pillars and red beams appeared and moved slowly across the sky. A nice surprise! Image taken with a Canon 10D.

This aurora was so faint we visually could not distinguish it from background light pollution. However, the camera revealed the presence of aurora. Canon Digital Rebel with a Sigma 24mm @ f1.8 - 30 Seconds @ ASA 400.

The clouds cleared up around 10:30pm and revealed this wonderful green light illuminating the northern skies. At some times, we saw great violet pillars over the green arc. A great show :) Nikon Coolpix 4500, 400ISO, approx. 30 seconds
