   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 29-Oct 31 2025 is 5.00 (NOAA Scale   
   G1).

   Rationale: G1 (Minor) conditions, with a chance for G2 (Moderate)   
   levels, are likely on 29-30 Oct due to the anticipated onset of a CH   
   HSS.   
      
   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 29-Oct 31 2025   
      
                 Oct 29  Oct 30  Oct 31   
   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 29-Oct 31 2025   
      
                 Oct 29        Oct 30        Oct 31

   R3 or greater    1%            1%            1%   
      
   Rationale: No R1 (Minor) or greater radio blackouts are expected.  No   
   significant active region flare activity is forecast.
