On May 10, 2024, a series of powerful solar storms brought a spectacular display of the Aurora Borealis (Northern Lights) to the Northern Hemisphere. The storms, which were the most powerful to affect Earth since March 1989, produced aurorae at far more equatorial latitudes than usual in both the Northern and Southern Hemispheres.

Living at 45°N latitude, auroras are sometimes visible, but typically they don't get too far above the horizon. The aurora of 10-11 May 2024 was unique in that its light, mostly the red component, covered the sky. Unfortunately, there was also a lot of cloud.
