   A. NOAA Geomagnetic Activity Observation and Forecast   
      
   The greatest observed 3 hr Kp over the past 24 hours was 5 (NOAA Scale   
   G1).   
   The greatest expected 3 hr Kp for Mar 28-Mar 30 2025 is 4.00 (below NOAA   
   Scale levels).

   21-00UT       4.00         3.33         2.33   
      
   Rationale: The geomagnetic field is expected to observe periods of G1   
   (Minor) geomagnetic storm levels on 28 Mar due to CH HSS influence.   
      
   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 28-Mar 30 2025   
      
                 Mar 28  Mar 29  Mar 30   
   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 R1 levels were observed over the past 24   
   hours. The largest was at Mar 27 2025 0037 UTC.   
      
   Radio Blackout Forecast for Mar 28-Mar 30 2025   
      
                 Mar 28        Mar 29        Mar 30

   R3 or greater    1%            1%            1%   
      
   Rationale: There exists a chance for R1-R2 (Minor-Moderate) radio   
   blackouts over 28-30 Mar.
