Overview
- Aurora was reported nationwide from major cities to the Alps, with the German Weather Service confirming the rare southward reach.
- A coronal mass ejection arrived in roughly 25 hours—exceptionally fast compared with the typical three to four days—and KP values above 8 were reported.
- Authorities noted possible impacts on satellites, navigation systems and high‑frequency radio, though large‑scale outages were not reported.
- The event aligns with the current solar maximum, which increases the likelihood of intense eruptions and low‑latitude auroral displays.
- Witnesses described vivid green, red and violet bands, while long‑exposure photos and smartphone night modes showed colors more strongly than the naked eye.
