Overview
- More than ten solar flares were recorded in 24 hours, including an X1.79 event on November 9 and an X1.21 flare on November 10.
- Researchers report a fast coronal mass ejection may overtake an earlier one, with both expected to reach Earth together late November 11 into November 12.
- The newer ejection was measured near the Sun at about 1,200 km/s versus roughly 720 km/s for the earlier event, increasing the chance of stronger effects.
- Forecasters expect G1–G2 geomagnetic storms late on November 11 with a potential rise to G3–G4 on November 12, and further strong flares remain possible.
- Off Japan’s Iwate Prefecture, a magnitude 6.7 quake on November 9 was followed by a 6.2 event and a 5.3 aftershock, with no reported casualties or nuclear plant issues; a Turkish seismologist separately warned of a possible M7–8 quake between Crete and Rhodes.
