My 5-minute music video features time-lapse movies of the Northern Lights shot in Churchill, Manitoba, Canada, over 5 nights from January 25 to 29, 2017, at the Churchill Northern Studies Centre. I was the instructor that week for a group of participants in the “Arctic Skies” Road Scholar program.
The auroras that week were typical of nightly Churchill displays, with the northern town under the auroral oval at 58° North latitude and 97° West longitude. During the displays the Kp Index was reading no higher than 3; most were at Kp 1 or 2. Nevertheless, the aurora puts on a good show on any clear night in winter. But displays with Kp indices higher than 3 or 4 are even more impressive. See my other aurora music videos here for examples from Churchill in 2016.
I shot the time-lapses with a Nikon D750 camera and Rokinon 12mm full-frame fish-eye and a Sigma 20mm lens, and a Canon 6D with a Sigma 8mm circular fish-eye lens. I shot about 3200 frames for the sequences here. Exposures varied from 1 second to 10 seconds per frame.
Frames were processed with Adobe Camera Raw and LRTimelapse, and assembled with Time-Lapse from Microprojects.ca using a 2- or 3-frame Tweening effect to smooth the motion.
