A superb display of aurora borealis seen on March 14, 2016 when it reached Level 5 storm levels. This during the substorm about 12:30 am when the display formed very nice converging zenith curtains. Here, the Big Dipper is at upper left. This was seen and shot from the Churchill Northern Studies Center, Churchill, Manitoba, with this image being one frame from some 2000 I shot this night as part of rapid-cadence time-lapse sequences. Frames were shot at f/1.4 with the Sigma 20mm lens and Nikon D750 using 1 to 2 second exposures.
The Big Dipper stars near the zenith seen through converging curtains of Northern Lights, March 9, 2016, at the Churchill Northern Studies Centre. This aurora was very green with little of the red tint at the tops of the curtains.
The great aurora display of March 6, 2016 when the sky was filled with curtains right at twilight. Green and magenta curtains of Northern Lights dance in the blue twilight. The Big Dipper is at left, the Pleiades at right. Taken as part of a time-lapse sequence at the Churchill Northern Studies Centre, for projection in digital planetariums.
