All-Sky Aurora May 10, 2024 - Wide-Angle Series V2.jpg
This is a series of images showing the evolution of the aurora borealis over about 80 minutes during the major storm of May 10/11, 2024. This version has the images arranged in two vertical columns.
These were with a full-frame fish-eye lens taking in a large sweep of the sky looking south at bottom and with the zenith overhead at top. The Kp Index reached a high level of Kp8 (on a scale of 0 to 9) this night, bringing auroras to the southern U.S., a rare occurence. The series shows the explosion of colour and structure a couple of times during short-lived sub-storms, then the dying down of activity after about 1 am local time to a dimmer though still sky-filling display of pulsating rays. Clouds moving through did obscure the view somewhat. The pinks from nitrogen were particularly bright during this show. They may be mixed with reds from oxygen.
The time between these 12 images is usually 8 minutes, though to include some interesting activity at a bright outburst, the interval is 5 minutes for three of the images around 1 am. The sequence starts with the show already well developed, as before that the camera was aimed north. I turned it to look south here a few minutes after the display began to explode in that direction, an unusual direction for bright curtains even from my latitude.
Each is a 7- or 9-second exposure taken as part of a time-lapse sequence using the 11mm TTArtisan lens at f/2.8 on the Canon R at ISO 800 or 1600. Taken from home in southern Alberta, at latitude 51º N. The original image is 13,000 by 27,000 pixels.
