Extreme Geomagnetic Storm Forecast Wavers After CMEs Do Not Reach Earth on Friday

Monitoring showed G1–G3 activity from a coronal hole, with the anticipated plasma clouds still unobserved.

Overview

  • By 20:00 Moscow time on November 7, space monitors had not detected the two plasma clouds ejected on November 5–6, the Solar Astronomy Laboratory of the Russian Academy of Sciences reported.
  • Earlier WSA‑ENLIL modeling indicated a potential G4–G5 impact on November 7, but scientists now say the delayed arrival could render that projection outdated.
  • Earth has been experiencing geomagnetic disturbances at G1–G3 levels tied to a coronal hole and early, faster fragments, with the main CME timing and trajectory remaining uncertain.
  • Researchers note the CMEs may have slowed or partially merged en route, and satellites at L1 would provide only short‑notice confirmation if a denser front approaches.
  • Experts caution that strong storms can disrupt power systems, satellites and navigation, advise vulnerable individuals to moderate exertion and alcohol, and say auroras could appear unusually far south if activity intensifies.
