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. Solar Radiation Storm Forecast for May 26-May 28 2024 May 26 May 27 May 28 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 No radio blackouts were observed over the past 24 hours. Radio Blackout Forecast for May 26-May 28 2024 May 26 May 27 May 28 R1-R2 40% 40% 40% R3 or greater 5% 5% 5% Rationale: A chance for R1 (Minor) blackouts exists on 26-28 May as Region 3679 rotates beyond the western limb.
