Overview
- Aurora were recorded between about 4:00 and 5:00 a.m. on Wednesday, with confirmed sightings from the Bavarian Alps and Baden‑Württemberg to parts of Lower Saxony including Hannover and Bremen.
- Unusually low‑latitude displays were also reported in the United States, including Florida, Texas, Arizona and Alabama.
- The Helmholtz Center reported Kp values near 8.7 and 8.3 and researchers confirmed a Ground Level Event detected by instruments worldwide.
- NOAA’s Space Weather Prediction Center issued G‑scale alerts for November 11–13 (G2, G3, G1), and DLR and ESA warned of potential disruptions to GPS, satellites and radio, with ESA noting signal interruptions on the dayside over parts of Europe, Africa and Asia.
- Experts say further auroral displays are possible over the next one to two nights, though timing is uncertain, and observers improve their chances with clear, dark northern views or by using smartphone night modes to capture faint colors.
