   A. NOAA Geomagnetic Activity Observation and Forecast   
      
   The greatest observed 3 hr Kp over the past 24 hours was 2 (below NOAA   
   Scale levels).   
   The greatest expected 3 hr Kp for Oct 23-Oct 25 2025 is 2.67 (below NOAA   
   Scale levels).

   Rationale: No G1 (Minor) or greater geomagnetic storms are expected.  No   
   significant transient or recurrent solar wind features are forecast.   
      
   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 23-Oct 25 2025   
      
                 Oct 23  Oct 24  Oct 25   
   S1 or greater   10%      1%      1%   
      
   Rationale: There is a slight chance for S1 (Minor) solar radiation storm   
   levels to be reached on 23 Oct associated with far-sided events. Chances   
   diminish by 24-25 Oct.   
      
   C. NOAA Radio Blackout Activity and Forecast   
      
   No radio blackouts were observed over the past 24 hours.   
      
   Radio Blackout Forecast for Oct 23-Oct 25 2025   
      
                 Oct 23        Oct 24        Oct 25

   R3 or greater    1%            1%            1%   
      
   Rationale: There is a slight chance for isolated R1-R2 (Minor-Moderate)   
   radio blackouts through 25 Oct.
