269 FXXX12 KWNP 091231 DAYDIS :Product: Forecast Discussion :Issued: 2026 May 09 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 continued at low levels this period. Region 4432 (N13W36, Dai/beta-gamma) continued to show signs of development, adding several intermediate and leader spots, and picking up a gamma configuration. This region produced most of the flare activity, including a C4.2 flare at 08/1551 UTC; the strongest of the period. A new area of flux emergence, with possible spots embedded, was noted rotating onto the NE limb near N19E89. Foreshortening prohibited proper identification and analysis, but this area will be monitored as it rotates onto the visible disk. The remaining regions were mostly unremarkable. No Earth-directed CMEs were detected in available coronagraph imagery. .Forecast... Solar activity is expected to be at predominately low levels over 09-11 May, with a chance for M-class (R1-R2/Minor-Moderate) flares and a slight chance for an X-class (R3-Strong or greater) flare. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux was at normal to moderate levels. The greater than 10 MeV electron flux was at background levels. .Forecast... The greater than 2 MeV electron flux is likely to reach high levels on 09-11 May. The greater than 10 MeV proton flux is expected to persist at background levels through 11 May. Solar Wind .24 hr Summary... The solar wind environment remained slightly enhanced under persistent, yet weakening, positive polarity CH HSS influences. Total magnetic field strength averaged near 4 nT, the Bz component was predominately neutral or northward throughout the period, and solar wind speeds averaged at a slightly elevated 500-550 km/s. Phi oscillated between a positive and negative orientation throughout the period. .Forecast... Solar wind parameters are expected to remain mildly enhanced through 11 May under positive polarity CH HSS influences. Geospace .24 hr Summary... The geomagnetic field was quiet and unsettled. .Forecast... The geomagnetic field is expected to be at quiet to unsettled levels on 09-11 May as positive polarity CH HSS influences persist.
