Overview
- NOAA’s Space Weather Prediction Center projects multiple CMEs to reach Earth between 11 and 13 November with alerts of G2 on Tuesday, G3 on Wednesday, and G1 on Thursday.
- Observers reported visible auroras over much of Baden‑Württemberg early Wednesday, with the brightest display around 04:00–04:30 local time, according to the Haus der Astronomie in Heidelberg.
- Astronomers say another display is possible Wednesday night, though there is no guarantee and precise timing remains uncertain.
- Forecast models note a faster CME from 10 November that may interact with a slower 9 November eruption, adding uncertainty to arrival windows and peak intensity.
- Germany’s weather service expects intervals of clear skies despite high thin clouds, while NOAA’s G‑scale highlights potential effects from radio and navigation disruptions to increased satellite drag at stronger storm levels.
