The grand sweep of the aurora borelis across the northern and northeastern sky, from Tibbitt Lake near Yellowknife, NWT, on September 8, 2018. The Big Dipper and Polaris are at left; Auriga and Taurus are rising at right, with Capella, Aldebaran and the Pleiades coming up in the east. Cassiopeia and Perseus are at top in the Milky Way. There’s a meteor streaking down at top as well! This is a mean-combined stack of 8 exposures for the ground to smooth noise, and one exposure for the sky, all 15 seconds at f/2.8 with the 12mm Rokinon full-frame fish-eye lens, and Nikon D750 at ISO 6400. This was part of a time-lapse, taken before the arc swept overhead while it was still across the north and east.
A 180° panorama of a developing aurora display near Yellowknife, NWT, at Tibbit Lake. This was September 8, 2018. The Kp Index was officially only 2! Yet the display developed into one of the best I have seen. This was early, as the arcs began to come overhead. The Big Dipper is left of centre to the northwest. Arcturus is reflected in the water. Capella is at centre amid the lower curtain, rising in the northeast. Vega is at upper left. The horizon glow at far left is Yellowknife about 70km away. This is a stitch of 9 segments, each 25 seconds with the 14mm Sigma Art lens at f/2.2, mounted portrait, and on the Nikon D750 at ISO 3200. Stitched with Adobe Camera Raw.
