   A. NOAA Geomagnetic Activity Observation and Forecast   
      
   The greatest observed 3 hr Kp over the past 24 hours was 3 (below NOAA   
   Scale levels).   
   The greatest expected 3 hr Kp for Nov 19-Nov 21 2025 is 4.00 (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 Nov 19-Nov 21 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   
      
   No radio blackouts were observed over the past 24 hours.   
      
   Radio Blackout Forecast for Nov 19-Nov 21 2025   
      
                 Nov 19        Nov 20        Nov 21

   R3 or greater    1%            1%            1%   
      
   Rationale: A slight chance for R1-2 (Minor-Moderate) radio blackouts due   
   to isolated M-class flare activity will persit through 21 Nov due to the   
   flare potential presented by AR 4284.
