   A. NOAA Geomagnetic Activity Observation and Forecast   
      
   The greatest observed 3 hr Kp over the past 24 hours was 4 (below NOAA   
   Scale levels).   
   The greatest expected 3 hr Kp for Oct 26-Oct 28 2025 is 5.00 (NOAA Scale   
   G1).

   21-00UT       2.33         2.67         5.00 (G1)   
      
   Rationale: G1 (Minor) conditions, with a chance for G2 (Moderate), are   
   likely on 28 Oct due to the anticipated onset of influence from a   
   positive polarity coronal hole.   
      
   B. NOAA Solar Radiation Activity Observation and Forecast   
      
   Solar radiation, as observed by NOAA GOES-18 over the past 24 hours, was   
   below S-scale storm level thresholds.   
      
   Solar Radiation Storm Forecast for Oct 26-Oct 28 2025   
      
                 Oct 26  Oct 27  Oct 28   
   S1 or greater    1%      1%      1%   
      
   Rationale: No S1 (Minor) or greater solar radiation storms are expected.   
   No significant active region activity favorable for radiation storm   
   production is forecast.   
      
   C. NOAA Radio Blackout Activity and Forecast   
      
   No radio blackouts were observed over the past 24 hours.   
      
   Radio Blackout Forecast for Oct 26-Oct 28 2025   
      
                 Oct 26        Oct 27        Oct 28   
   R1-R2           10%           10%           10%   
   R3 or greater    1%            1%            1%   
      
   Rationale: A slight chance for isolated R1-R2 (Minor-Moderate) radio   
   blackouts continues over 26-28 Oct.
