3-day Solar-Geophysical Forecast
:Product: 3-Day Forecast :Issued: 2025 Jun 14 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 6 (NOAA Scale G2). The greatest expected 3 hr Kp for Jun 14-Jun 16 2025 is 6.00 (NOAA Scale G2). NOAA Kp index breakdown Jun 14-Jun 16 2025 Jun 14 Jun 15 Jun 16 00-03UT 4.67 (G1) 5.00 (G1) 4.67 (G1) 03-06UT 5.33 (G1) 4.33 4.00 06-09UT 5.67 (G2) 3.67 3.33 09-12UT 4.33 3.33 3.00 12-15UT 3.33 2.67 3.00 15-18UT 4.67 (G1) 3.00 2.33 18-21UT 5.00 (G1) 3.00 2.33 21-00UT 6.00 (G2) 4.00 3.00 Rationale: Periods of G1-G2 (Minor-Moderate) geomagnetic storms are expected on 14 Jun due to CME and CH HSS influences. Periods of G1 (Minor) storming are likely on 15-16 Jun 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 Jun 14-Jun 16 2025 Jun 14 Jun 15 Jun 16 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 Jun 13 2025 2110 UTC. Radio Blackout Forecast for Jun 14-Jun 16 2025 Jun 14 Jun 15 Jun 16 R1-R2 40% 40% 40% R3 or greater 5% 5% 5% Rationale: There is a chance for R1-R2 (Minor-Moderate) radio blackouts over 14-16 Jun.
