  • Impact Summary

    • Next 24 hours: No risk of radio blackouts.
    • No risk of solar radiation storms.
    • Geomagnetic outlook: No G1 (Minor) or greater geomagnetic storms are expected.
    • No significant transient or recurrent solar wind features are forecast.
    • Radiation outlook: No S1 (Minor) or greater solar radiation storms are expected.
    • No significant active region activity favorable for radiation storm production is forecast.
    • Radio blackout outlook: There is a chance for R1-R2 (Minor-Moderate) radio blackouts on 11-13 Sep.

Long Term Forecast

  • Forecast of Solar and Geomagnetic Activity 08 September - 04 October 2025: Solar activity is expected to be mostly low, with a chance for moderate (R1-R2/Minor-Moderate) activity due to multiple complex regions on the visible disk and expected to return from the Sun’s farside.
  • No proton events are expected at geosynchronous orbit.
  • The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels over 08-11 Sep and 20-21 Sep due to multiple, recurrent CH HSSs. The remainder of the outlook period is expected to be at normal to moderate levels.
  • Geomagnetic field activity is expected to range from quiet to G1 (Minor) geomagnetic storm levels.
  • G1 conditions are likely on 15 Sep; active conditions are likely on 08 Sep, 14 Sep, 16 Sep, 28-29 Sep, and 03-04 Oct; unsettled conditions are likely on 09-10 Sep, 17-19 Sep, and 30 Sep.
  • All increases in geomagnetic activity are anticipated from multiple, recurrent CH HSSs. The remainder of the outlook period is likely to be mostly quiet.
