This is a panorama of a substorm outburst during the great May 10, 2024 display of Northern Lights, here creating an overhead corona with rays converging to the magnetic zenith (south of the true zenith), and amid clouds. The rays show a rich mix of oxygen greens and reds, as well as nitrogen blues blending to create purples. Some green and red are mixing to make yellows. South is at centre here. The bright star Arcturus is below the zenith point. The constellation of Corona Borealis (fittingly!) is left of the convergence point. The distortion from the equirectangular panorama projection stretches the sky at top, so that rays that should be radial look like straight parallel beams. Nevertheless, this serves to illustrate the basic structure and colours of a zenith corona outburst. Two other cameras are in the frame taking images or movies. This is a panorama of 9 segments, each a 4-second exposure with the Laowa 15mm lens at f/2 on the Canon Ra at ISO 400, with the camera turned to portrait orientation. Stitched with PTGui. Adobe DeNoise AI applied to the pan segments. Taken from home in southern Alberta, Canada.
