   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 Apr 09-Apr 11 2025 is 4.67 (NOAA Scale   
   G1).

   Rationale: G1 (Minor) geomagnetic storming is expected on 09 Apr under   
   negative polarity CH HSS effects.   
      
   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 09-Apr 11 2025   
      
                 Apr 09  Apr 10  Apr 11   
   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 08 2025 2222 UTC.   
      
   Radio Blackout Forecast for Apr 09-Apr 11 2025   
      
                 Apr 09        Apr 10        Apr 11   
   R1-R2           40%           40%           40%   
   R3 or greater    5%            5%            5%   
      
   Rationale: A chance for R1-2 (Minor-Moderate) radio blackouts will   
   persist through 11 Apr primarily due to the flare potential observed in   
   ARs 4048 and 4054.
