A lone observer gazes at an array of colourful curtains of aurora during an active display, March 6, 2016, with curtains in the evening twilight adding blue tints to the sky and tops of the curtains, as well as the greens and reds from oxygen. Curtains toward the horizon are more yellow due to atmospheric extinction. Jupiter is rising at left, then near opposition.
A lone observer gazes skyward at the start of a wonderful aurora display on March 6, 2016, as the curtains begin to appear and dance in the deep blue twilight. This was at the Churchill Northern Studies Centre, Churchill, Manitoba.
Orion rising behind the iconic Hoodoos on Highway 10 east of Drumheller, Alberta, near East Coulee, on a moonless January night, with illumination by starlight and by a nearby yardlight providing some shadows and warmer illumination. Clouds are beginning to move in and are providing the natural star glows. This is a stack of 10 x 10-second exposures for the ground, mean combined to smooth noise, plus one 10-second exposure for the sky to minimize trailing. All at f/2.8 with the 24mm Sigma Art lens and Nikon D750 at ISO 3200. Taken January 10, 2016.
