A classic auroral arc across the northern sky, from home in southern Alberta. This was January 4, 2019. For a brief while some yellow-tinted streamers appeared amid the classic green and red glows from oxygen. Polaris, marking due north, and the Little Dipper lie high and to the left of centre here. The Big Dipper is low on the horizon at centre. This is a single 15-second exposure with the Laowa 15mm lens at f/2 and Sony a7III at ISO 1250.

The arc of the classic auroral oval across the northern sky, from home in southern Alberta. This was January 4, 2019. The oval is centered on a point east of due north, as from my location magnetic north lies offset about 13° east of due north. Polaris, marking due north, and the Little Dipper lie high and to the left of centre here. The Big Dipper is low on the horizon at centre. This is a single 20-second exposure with the Laowa 15mm lens at f/2 and Sony a7III at ISO 1600.
