Strong Geomagnetic Activity Detected

As of November 6, a G3 (strong) geomagnetic storm is ongoing, according to NOAA’s Space Weather Prediction Center. The G3 level was recorded at 05:27 UTC on November 6, influenced by a continuous coronal mass ejection (CME).

Coronal Mass Ejection Impact

A CME is expected to reach Earth as early as Thursday evening, November 6 (EST). This interaction may intensify current geomagnetic activity and affect satellite operations and power systems in some regions.

Solar Flare Event

On November 4 at approximately 12:34 EST, an R3-level radio blackout event occurred, originating from active solar Region 4274.

The last R3-class event took place on June 19 of this year.

Summary

Strong geomagnetic and solar flare activity observed this week, driven by active CME influence, may cause moderate disruptions to space- and ground-based systems.

Author’s summary: NOAA confirms a G3 geomagnetic storm in progress and notes a significant R3 solar flare from Region 4274, signaling heightened solar activity and potential system disruptions.
