Fisheye panorama image 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. A purple arc stretches high across the sky 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 purple 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 over the house at left. The Big Dipper is at top left. Photographed from southern Alberta, Canada. | |
