Aurora at Zenith #5 (March 23, 2023).jpg
A framing of the converging rays of aurora overhead at the magnetic zenith, a little south of the true zenith at 90° altitude. This was the superb Kp6 to 7 display on March 23, 2023, with the aurora in a pulsating mode rather than forming rippling curtains. Leo is just below the convergence point. The Big Dipper is at top. At this time later in the display the rays showed a lot of red as well as green. A short exposure helped freeze the rapid pulsations and capture the structure.
This is a single 2-second exposure with the Venus Optics 15mm lens at f/2 and Canon R6 at ISO 2500.
