The U.S. National Oceanic and Atmospheric Administration (NOAA) has issued updated forecasts indicating continued geomagnetic activity through the remainder of June. While no severe space weather events are expected, NOAA’s Space Weather Prediction Center (SWPC) warns that minor disturbances may affect power systems, satellite operations, and high-frequency communications at various intervals.
According to NOAA’s 27-day outlook released on June 2, several periods of G1-class (minor) geomagnetic storm conditions are likely between June 9 and June 30. The forecast reflects the ongoing solar activity tied to Solar Cycle 25, which is approaching its peak phase. While no significant coronal mass ejections (CMEs) are currently directed at Earth, sunspot activity remains elevated, and M-class solar flares may continue to impact upper atmospheric conditions and shortwave radio bands.
Daily three-day forecasts show fluctuating ap and Kp indices, with SWPC meteorologists monitoring solar wind speed and magnetic field orientation for potential short-term disruptions. These conditions may lead to brief GPS signal degradation, minor satellite drag issues in low Earth orbit, and occasional high-frequency radio blackouts in polar and high-latitude regions.
Operators of critical infrastructure are advised to remain alert, particularly energy grid managers and satellite communication providers. NOAA encourages the public to follow official alerts on the SWPC website and notes that auroral displays may be visible during clear nights in parts of Alaska, Canada, and the northern continental United States.
The agency emphasized that while the risk of a severe storm remains low for the rest of June, elevated solar activity is likely to persist through the coming weeks, with additional updates to be provided as conditions evolve.
