Aurora Rays Over House #2 (March 23, 2023).jpg

Add to Cart Add to Lightbox Download
Auroral streamers or rays rather than classic curtains as part of the pulsating phase of the great equinox display of Northern Lights on March 23, 2023. The rays have a strong vertical structure from precipitating electrons but were pulsing off and on rather than rippling. While the predominent colour is green, there is a lot of red and magenta mixed in. The rays are converging upward to the magnetic zenith. This is looking northwest over my house. A short exposure froze the motion and pulsations to better record the structure. Cassiopeia is at centre. The Pleiades are at left.

This is a single 1-second exposure with the Venus Optics 15mm lens at f/2 and the Canon R6 at ISO 6400. Taken from home in southern Alberta.
