Strong (G3) Geomagnetic Storms Observed - 05 Aug 2023

Strong (G3) Geomagnetic Storms Observed - 05 Aug 2023
published: Monday, August 07, 2023 11:17 UTC

Strong (G3) geomagnetic storm conditions were observed at 0559 UTC on 05 Aug 2023 following the arrival of a CME. Moderate and Strong (G2-G3) geomagnetic storms are expected to continue until 1200 UTC on 05 Aug.    

Other significant activity over the day included an R3 (Strong) radio blackout at 05/2221 UTC from Region 3386. A CME was associated with the event and is currently being analyzed and modeled to determine if/when Earth might see geomagnetic effects as it propagates through the solar system.
