   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 Mar 31-Apr 02 2025 is 3.00 (below NOAA   
   Scale levels).

   Rationale: No G1 (Minor) or greater geomagnetic storms are expected.   
      
   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 Mar 31-Apr 02 2025   
      
                 Mar 31  Apr 01  Apr 02   
   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 Mar 30 2025 1642 UTC.   
      
   Radio Blackout Forecast for Mar 31-Apr 02 2025   
      
                 Mar 31        Apr 01        Apr 02   
   R1-R2           55%           50%           50%   
   R3 or greater   10%           10%           10%   
      
   Rationale: R1-R2 (Minor-Moderate) radio blackouts are likely on 31 Mar,   
   with a chance for up to R2 events persists through 02 Apr. A slight   
   chance for R3 (Strong) events exists for 31 Mar - 02 Apr.
