Moderate (G2) Geomagnetic Storm Observed Following CME Arrival
US · Published Aug 3, 2026
The National Oceanic and Atmospheric Administration (NOAA) has reported that the geomagnetic field reached G2 (Moderate) storm levels on August 2, 2026, at 17:59 UTC.
This activity was triggered by the arrival of a coronal mass ejection (CME).

Impact & Risks

The G2 (Moderate) geomagnetic storm may cause potential disruptions to high-frequency (HF) radio communications, particularly on the sunlit side of the Earth. Low-frequency navigation signals could also experience brief degradation. While these effects are not expected to be severe, they may impact aviation, maritime, and emergency communication systems. Power grid fluctuations are possible, but widespread outages are not anticipated at this level of geomagnetic activity.
