March 23, 2023 - A 360 degree fish-eye panorama of the great equinox aurora in southern Alberta, Canada, 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, looking a little like a STEVE arc (but it isn't), with a green band below it to the south. 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 bottom), to west (at right toward the sunset twilight) and north (at top). The zenith is at centre where the rays of the puple arc converge. The crescent Moon and Venus shine above the bright twilight arch. Orion and the winter stars are below centre. Leo and the spring stars are rising at left. The Big Dipper is at top left.
