Overview
- Planetary-scale disturbances began overnight on Nov. 6, with the geomagnetic index registering G2–G3.
- The second eruption, rated M8.65 with a peak at 01:07 and an estimated speed near 1,000 km/s, is larger and faster than the first and could overtake it.
- Early propagation models omitted the latest burst, and researchers say updated runs are expected to strengthen Friday's forecast.
- Scientists report that recent limb eruptions are spreading wider and traveling faster than anticipated, helping explain the stronger-than-expected impacts now observed.
- Potential effects include shortwave communication and navigation disruptions, grid voltage fluctuations, and wider auroral visibility, with disturbances expected to persist about a day as the main plasma mass arrives.
