   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 Feb 10-Feb 12 2026 is 2.67 (below NOAA   
   Scale levels).

   Rationale: No G1 (Minor) or greater geomagnetic storms are expected over   
   10-12 Feb.   
      
   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 Feb 10-Feb 12 2026

   S1 or greater   25%     25%     25%   
      
   Rationale: There is a chance for S1 (Minor) or greater solar radiation   
   storms on 10-12 Feb due to the flare potential and location of Region   
   4366.   
      
   C. NOAA Radio Blackout Activity and Forecast   
      
   Radio blackouts reaching the R1 levels were observed over the past 24   
   hours. The largest was at Feb 09 2026 0227 UTC.

   R3 or greater   25%           25%           25%   
      
   Rationale: R1-R2 (Minor-Moderate) radio blackouts are likely, with a   
   chance for R3 (Strong) or greater events, on 10-12 Feb.
