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 May 29-May 31 2024 is 4.00 (below NOAA Scale levels). NOAA Kp index breakdown May 29-May 31 2024 May 29 May 30 May 31 00-03UT 0.67 3.00 1.67 03-06UT 1.67 2.67 1.33 06-09UT 2.00 2.00 1.33 09-12UT 2.00 1.67 1.33 12-15UT 2.33 1.33 1.33 15-18UT 4.00 1.67 1.33 18-21UT 4.00 2.00 1.67 21-00UT 2.67 2.00 1.67 Rationale: There is a chance for G1 (Minor) storming on 29 May with any shock arrival from the 27 May CME. 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 May 29-May 31 2024 May 29 May 30 May 31 S1 or greater 10% 10% 10% 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 May 29-May 31 2024 May 29 May 30 May 31 R1-R2 60% 60% 60% R3 or greater 30% 30% 30% Rationale: (R1-2/Minor-Moderate Radio Blackouts) are likely, while a chance remains for isolated (R3/Strong Radio Blackouts) through 31 May.
