B. NOAA Solar Radiation Activity Observation and Forecast Solar radiation, as observed by NOAA GOES-16 over the past 24 hours, was below S-scale storm level thresholds. Solar Radiation Storm Forecast for Mar 02-Mar 04 2021 Mar 02 Mar 03 Mar 04 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 Mar 02-Mar 04 2021 Mar 02 Mar 03 Mar 04 R1-R2 1% 1% 1% R3 or greater 1% 1% 1% Rationale: No R1 (Minor) or greater radio blackouts are expected.
