Solar activity reached low levels. Multiple C-class flares were observed from a region just beyond the E limb. The largest flare was a C3.8 at 05/0305 UTC. Region 3630 (S11W24, Bxi/beta) also produce a C2.0 flare at 05/1307 UTC. Slight growth was observed in Region 3630 and 3629 (N06W28, Cao/beta). No Earth-directed CMEs were observed. .Forecast... Solar activity is expected to be at very low to low levels through 08 Apr. Energetic Particle .24 hr Summary... The greater than 10 MeV proton flux was at background levels. The greater than 2 MeV electron flux was at normal to moderate levels. .Forecast... The greater than 10 MeV proton flux is expected to remain at background levels. The greater than 2 MeV electron flux is expected to continue at normal to moderate levels through 08 Apr. Solar Wind .24 hr Summary... Solar wind parameters were mildly enhanced under negative polarity CH HSS conditions. Solar wind speed ranged from 401-476 km/s. Total field ranged from 2-7 nT while the Bz component was between +/-6 nT. Phi angle was mostly negative. .Forecast... Solar wind conditions are expected to slowly diminish to background levels on 06 Apr. Nominal solar wind conditions are expected on 07-08 Apr. Geospace .24 hr Summary... The geomagnetic field was quiet and unsettled. .Forecast... The geomagnetic field is expected to be quiet and unsettled on 06 Apr. Mostly quiet conditions are expected on 07-08 Apr. ####018002151#### FXXX10 KWNP 060031 DAYTDF :Product: 3-Day Forecast :Issued: 2024 Apr 06 0030 UTC # Prepared by the US Dept. of Commerce, NOAA, Space Weather Prediction Center # Product description and SWPC contact on the Web # http://www.swpc.noaa.gov/wwire.html # # 3-Day Forecast # A. 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 Apr 06-Apr 08 2024 is 3.00 (below NOAA Scale levels).

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 Apr 06-Apr 08 2024 Apr 06 Apr 07 Apr 08 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 Apr 06-Apr 08 2024 Apr 06 Apr 07 Apr 08 R1-R2 5% 5% 5% R3 or greater 1% 1% 1% Rationale: No R1 (Minor) or greater radio blackouts are expected. No significant active region flare activity is forecast.
