Auroral Arc Panorama at Moonrise (July 25, 2024).jpg

Add to Cart Add to Lightbox Download
A 270° panorama of the surprise aurora of July 25, 2024, as there was little indication in the day or two before that an aurora was possible this night. But the Kp Index did reach Kp5, which is enough to produce a good display from my location in southern Alberta. Locations farther south in the northern U.S. also saw some Lights this night. This showing of Northern Lights exhibits the classic arc of an aurora centered on the direction of magnetic north, to the north-northeast from my location.

I shot this panorama shortly after moonrise, with the waning gibbous Moon in the southeast at right. Due north is at centre, with the Big Dipper left of centre and Arcturus over my house. Cassiopeia is right of centre. The view to the east at right is over a canola field.

Technical:
This is a panorama of 5 segments, with the Laowa 10mm Zero-D lens wide open at f/2.8 on the Nikon Z6III at ISO 1600 and each 20-second exposures. Stitched with PTGui, though even it had difficulty aligning the segments due to the distortion of such a wide lens, despite the lens being in the PTGui database. Manual control point alignment was required as well as manual mask adjustments. Stitched with equirectangular projection. Adobe DeNoise AI applied to the segments before stitching.
