Panorama of the great equinox aurora of 23 March 2023, with the aurora already bright as the sky darkened at twilight. The Kp values peaked at Kp7 this night. A purple arc stretches high across the sky, with a green band below it. The green arc has some of the features of a 'dunes' aurora in that it shows horizontal streaks. This is looking east (at left) to south (at centre), to west (right of centre toward the sunset twilight) and north (at either end). The zenith is at top where the rays of the purple arc converge. The crescent Moon and Venus shine above the bright twilight arch. Orion and the winter stars are at centre. Leo and the spring stars are rising over my house at left. The Big Dipper is at far left, distorted by the panorama projection. Photographed from southern Alberta, Canada.
