   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 19-Feb 21 2026 is 3.67 (below NOAA   
   Scale levels).

   Rationale: No G1 (Minor) or greater geomagnetic storms are expected.  No   
   significant transient or recurrent solar wind features are forecast.   
      
   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.

   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   
      
   No radio blackouts were observed over the past 24 hours.   
      
   Radio Blackout Forecast for Feb 19-Feb 21 2026

   R3 or greater    1%            1%            1%   
      
   Rationale: Solar activity is expected to be at low levels, with a slight   
   chance for M-class (R1-R2/Minor-Moderate) flares through 21 Feb.
