      :Product: 3-Day Forecast :Issued: 2025 Dec 22 0030 UTC # Prepared by the   
      U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center # 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 Dec 22-Dec 24 2025 is 5.00 (NOAA Scale G1). NOAA Kp index

      2.67 3.67 21-00UT 4.67 (G1) 3.67 3.67 Rationale: G1 (Minor) geomagnetic   
      storms are likely on 22-23 Dec due to CH HSS influences. 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 Dec 22-Dec 24 2025 Dec 22   
      Dec 23 Dec 24 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 Radio blackouts reaching the R1 levels were   
      observed over the past 24 hours. The largest was at Dec 21 2025 1827 UTC.   
      Radio Blackout Forecast for Dec 22-Dec 24 2025 Dec 22 Dec 23 Dec 24 R1-R2   
      25% 25% 30% R3 or greater 1% 1% 1% Rationale: There is a chance for R1   
      (Minor) or greater radio blackouts through 24 Dec.
