Overview
- Overnight displays were reported across Baden-Württemberg, with red, pink and green aurora visible to the naked eye around 04:00 to 04:30, according to the Haus der Astronomie in Heidelberg.
- NOAA’s Space Weather Prediction Center maintains alerts tied to multiple CMEs: G2 on 11 November, G3 on 12 November and G1 on 13 November.
- Forecasters note uncertainty over whether the faster 10 November CME will overtake the earlier eruption, which could shift the arrival window and the strength of any aurora.
- Observers in Lower Saxony also reported activity, and some local experts expect stronger conditions in the coming night, though they stress that another show is not guaranteed.
- No major technical impacts were reported, but NOAA’s G-scale outlines possible effects on power grids, satellites and radio/navigation systems if storms intensify.
