Red Aurora Panorama (Feb 26, 2022).jpg
A 300° panorama of an aurora from the Churchill Northern Studies Centre, in Churchill, Manitoba on February 26, 2022. This aurora was at Kp1 level (very low) and appeared only as featureless grey arcs to the eye. But the camera picked up unusual red colouration, and even some yellow-oranges, along with the more normal greens. The reds are odd for such a low-level aurora as the oxygen reds typically appear only when the aurora gets very active and energetic. The display did brighten more later this night when it took on the more classic green arcs, with occasional lower fringes of nitrogen pinks. But at the start of the night the reds dominated. Orion is at far left (southwest) while Leo is at far right (east). The winter Milky Way arches over the Studies Centre. This is a panorama of 6 segments with the TTArtisan 11mm full-frame fish-eye lens at f/2.8 for 30 seconds each with the Canon Ra at ISO 3200. Stitched with PTGui.
