All-Sky Aurora Outburst Series (Sept 16, 2024).jpg
This is a series of 20 images recording a short-lived substorm outburst during the Kp6-8-level aurora display on the night of September 16, 2024, shot from home in southern Alberta, Canada.
The images were taken over a span of just 9 minutes as part of a time-lapse sequence, with 6-second-long frames taken at a cadence of 7 seconds (i.e. a 1s interval between frames), with every 4th image selected for this montage, so at an interval of 28s seconds apart, to show the rapid changes in shape and colour during this fast sub-storm outburst.
Like a printed page, time runs from left to right across each row, then down to the later row below. So from top left to bottom right. Times are Mountain Daylight Time.
The field of view is 180° across the circular images, with the camera tipped down toward the south, at bottom. The zenith is at the centre of the frames. The bright Moon a day before full is at left rising in the southeast.
The outburst begins with a difuse arc to the south, but with rays beginning to appear converging to the zenith. Within less than a minute the sky fills with green curtains, converging to a bright zenith show with intense pinks and reds. The aurora fills the sky with rapidly changing rays and curtains. But after just 9 to 10 minues the outburst is beginning to break up into pulsating rays and patches converging to the magnetic zenith at centre, in a recovery phase after the short-lived sub-storm.
Each still frame was a 6-second exposure at f/2 with the TTArtisan 7.5mm circular fish-eye lens, on the Nikon Z6III at ISO 400.
To prospective publishers — Individual images can be supplied to facilitate layout in a different format if desired. The original of this matrix of images is ~20,800 x 20,160 pixels. Each frame is 5200 x 4032 pixels, cropped in from the 24 Mp size of the Nikon Z6III images.
