   A. NOAA Geomagnetic Activity Observation and Forecast   
      
   The greatest observed 3 hr Kp over the past 24 hours was 8 (NOAA Scale   
   G4).   
   The greatest expected 3 hr Kp for Jun 02-Jun 04 2025 is 7.67 (NOAA Scale   
   G4).

   Rationale: UP to G4 (Severe) geomagnetic storms are likely on 02 Jun   
   due to effects from a CME that left the Sun on 31 May. G1-G2   
   (Minor-Moderate) geomagnetic storms are likely on 03 Jun due to 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   
   above S-scale storm level thresholds.

   S1 or greater   99%     75%     60%   
      
   Rationale: S1-S2 (Minor-Moderate) solar radiation storms are likely   
   persist over 02-03 Jun becoming likely on 04 Jun.   
      
   C. NOAA Radio Blackout Activity and Forecast   
      
   No radio blackouts were observed over the past 24 hours.

   R3 or greater   15%           15%           15%   
      
   Rationale: R1-R2 (Minor-Moderate) radio blackouts are likely, with a   
   slight chance for R3 (Strong), over 02-04 Jun.
