   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 Apr 12-Apr 14 2025 is 4.67 (NOAA Scale   
   G1).

   Rationale: G1 (Minor) geomagnetic storm levels are likely on 12 Apr due   
   to CH HSS activity.   
      
   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 Apr 12-Apr 14 2025

   S1 or greater    5%      5%      5%   
      
   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 R1 levels were observed over the past 24   
   hours. The largest was at Apr 11 2025 1650 UTC.   
      
   Radio Blackout Forecast for Apr 12-Apr 14 2025   
      
                 Apr 12        Apr 13        Apr 14   
   R1-R2           50%           50%           50%   
   R3 or greater    5%            5%            5%   
      
   Rationale: There is an increased chance for M-class flares (R1-R2,   
   Minor-Moderate) on 12-14 Apr due primarily to the flare potential from   
   Regions 4055 and 4060.
