The night sky on the night of the great aurora of May 2024 — 10 May 2024

On the night of 10–11 May 2024 the strongest geomagnetic storm in more than twenty years — the first G5 'extreme' storm since 2003 — lit up skies far from the poles. Auroras were photographed across Europe and North America, often far further south than usual, and in the southern hemisphere too. The storm was driven by a series of coronal mass ejections from sunspot region AR3664.
