290 FXXX12 KWNP 291231 DAYDIS :Product: Forecast Discussion :Issued: 2024 Apr 29 1230 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 # # Forecast Discussion # Solar Activity .24 hr Summary... Solar activity reached moderate levels. Region 3654 (S07W43, Ekc/beta-gamma-delta) produced two R1 (Minor) events; an M2.5 flare at 29/0048 UTC and an M3.7 flare at 29/0111 UTC. Region 3654 continued a trend of growth, especially in the intermediate and trailer spots, and maintained a delta magnetic configuration in the largest intermediate spot. New Regions 3661 (N23E69, Hsx/alpha) and 3662 (N30E46, Cro/beta) were numbered this period. The remaining regions were either stable or in decay. Other activity included an eruption near N13W09 at 29/0909 UTC, though no coronagraph imagery for this event is yet available. No Earth-directed CMEs were detected in available imagery. .Forecast... Solar activity is expected to be at low levels over 29-30 Apr and 01 May with a chance for M-class flare (R1-R2/Minor-Moderate) activity. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux was at normal to moderate levels and the greater than 10 MeV proton flux was steady at background levels. .Forecast... The greater than 2 MeV electron flux is expected to be at normal to moderate levels over 29-30 Apr and 01 May. The greater than 10 MeV proton flux is expected to persist at background levels over 29-30 Apr and 01 May. Solar Wind .24 hr Summary... The solar wind environment was mildly enhanced due to positive polarity CH HSS influences. Total field strength reached a peak of 8 nT and the Bz component was varied between +6/-4 nT. Solar wind speeds slowly increased from from 400 km/s to around 450-500 km/s as the period progressed. The phi angle was predominantly positive throughout the period. .Forecast... Enhanced solar wind conditions are likely over 29-30 Apr and 01 May due to CH HSS influences and possible transient activity. Geospace .24 hr Summary... The geomagnetic field was quiet. .Forecast... Geomagnetic field activity is expected to range from quiet to unsettled levels on 29-30 Apr, and quiet to active levels on 01 May, due to the anticipated influence of CH HSSs combined with potential transient activity.
