A 150° panorama of the auroral arc across the northern sky, shot from home in Alberta on April 27, 2022. The camera picked up the blue colour at the top of the curtains at left in the northwest from high-altitude sunlight illuminating the tops of the curtains. Otherwise, oxygen reds and greens dominate this fairly quiet display. Coincidentally, the arc of the aurora nicely follows the arc of the Milky Way across the north, then at its lowest for the year in the spring sky.
