   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 Nov 04-Nov 06 2025 is 4.67 (NOAA Scale   
   G1).

   Rationale: G1 (Minor) geomagnetic storms are likely on 06 Nov due to   
   CME/HSS arrival.   
      
   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 Nov 04-Nov 06 2025

   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   
      
   Radio blackouts reaching the R2 levels were observed over the past 24   
   hours. The largest was at Nov 03 2025 1011 UTC.   
      
   Radio Blackout Forecast for Nov 04-Nov 06 2025

   R3 or greater   10%           10%           10%   
      
   Rationale: R1-R2 (Minor-Moderate) radio blackouts are likely, with a   
   slight chance for an isolated (R3-Strong) event through 06 Nov.
