Bring on the blue auroras!
This is a blue-topped arc of Northern Lights on the evening of May 15, 2026 during a Kp5-level storm. The sky is still bright and deep blue with twilight and the tops of the auroral curtains are lit blue by sunlight interacting with high-altitude nitrogen. Below, the curtains are tinted magenta, from the red of oxygen and blue of nitrogen mixing, while at bottom the curtains are glowing from normal oxygen green.
This is looking north at left of centre, with east to the right, and northwest with the sunset glow at left. I have left in the satellite trails.
This was from home in southern Alberta at 51ยบ N.
Technical:
A panorama of 4 segments each 15 seconds at f/2 with the Nikkor 20mm S-Line lens on the Nikon Z6III at ISO 800. Stitched in Camera Raw.
