   A. NOAA Geomagnetic Activity Observation and Forecast   
      
   The greatest observed 3 hr Kp over the past 24 hours was 6 (NOAA Scale   
   G2).   
   The greatest expected 3 hr Kp for Apr 06-Apr 08 2025 is 5.67 (NOAA Scale   
   G2).

   Rationale: G1-G2 (Minor-Moderate) geomagnetic storms are expected on 06   
   Apr due to continued coronal hole 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 Apr 06-Apr 08 2025   
      
                 Apr 06  Apr 07  Apr 08   
   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 05 2025 2005 UTC.   
      
   Radio Blackout Forecast for Apr 06-Apr 08 2025   
      
                 Apr 06        Apr 07        Apr 08

   R3 or greater   15%           10%           10%   
      
   Rationale: R1-R2 (Minor-Moderate) radio blackouts are likely, with a   
   slight chance for R3 (Strong), over 06-08 Apr.
