Blue Aurora Panorama – May 10, 2024 (Rectangular Version)
Blue Aurora Panorama – Rectangular (May 10, 2024).jpg
This is a 360° panorama of the May 10/11, 2024 great aurora display, when the Kp Index reached 8 this night bringing aurora to as far south as the southern U.S. Here, from my home in southern Alberta, Canada (latitude 51° N) it is exhibiting very odd vertical blue and magenta rays across the western (left), and northern and eastern sky (centre), and an odder bright patch to the south at far right. This was toward the end of the main activity of the show for me this night, at about 2:30 am. These distinctive blue rays appeared like this only at this time after the main show died down. The colours were not visible to the eye but showed up even on the live screen of the camera. The blue could be coming from sunlight illuminating and interacting with the tops of the auroral curtains, though in this case the blue rays are extending down to the lower ends of the rays. Very odd!
The more normal green aurora is far to the south on my horizon at right, and to the west at far left, though that is toward the light dome of Calgary. The bright light on the horizon at right is one of the local farmers getting the seeding done.
The panorama is an equirectangular projection spanning 360º, and reaching almost to the zenith 90° high at top. But the projecton of the round sky onto a rectangular frame stretches and distorts the sky, including stars and aurora, at the top.
This a stitch of 20 segments, each 13-second exposures, with the Laowa 15mm lens at f/2 on the Canon Ra camera at ISO 800, and turned to portrait orientation. Processed in Camera Raw and stitched with PTGui. I could have shot only 8 to 10 segments here to make the pano work.
