Geomagnetic Storms - NOAA / NWS Space Weather Prediction …
A geomagnetic storm is a major disturbance of Earth's magnetosphere that occurs when there is a very efficient exchange of energy from the solar wind into the space environment surrounding Earth. These storms result from variations in the solar wind that produces major changes in the currents, plasmas, and fields in Earth’s magnetosphere.

HF Radio: Weak or minor degradation of HF radio communication on sunlit side, occasional loss of radio contact. Navigation: Low-frequency navigation signals degraded for brief intervals. An M6.7 flare was observed at 11/1549 UTC from old Region 3912 just around the east limb. Stay tuned for updates!
CME Arrival at Earth has Occurred and Warnings have been Issued
2024年10月12日 · The anticipated coronal mass ejection (CME) arrived at Earth at 11:15am EDT at nearly 1.5 million miles per hour. The CME strength and structure are being closely scrutinized for potential geomagnetic storm intensity, but, G3 levels are now expected due to the magnitude and potential of the CME, therefore G3 or greater warning has been issued.
