Overview
- A powerful solar eruption on 11 November sent fast coronal mass ejections that reached Earth overnight, producing rare low‑latitude auroras across France.
- The NOAA Space Weather Prediction Center reported a G4‑level storm beginning around 01:20 in Paris time, and French sightings were most frequent between roughly 03:00 and 05:30.
- Observations and images arrived from Île‑de‑France, Normandy, Bordeaux, Béarn, Haute‑Savoie, the Alps and Haute‑Provence.
- Space‑weather centers cautioned that further waves are possible between about 23:00 and 03:00, with visibility hinging on magnetic conditions, cloud cover and light pollution.
- Scientists attribute the increased activity to the Sun nearing solar maximum, and observers are advised to face north, find dark skies or rely on reputable webcams and real‑time tools.
