882 FXXX12 KWNP 301231 DAYDIS :Product: Forecast Discussion :Issued: 2025 Nov 30 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 was at moderate levels with four M-flares (R1-Minor) observed from Regions 4294 (S15E62, Fkc/beta-gamma) and new Region 4295 (N04E72, Hsx/alpha); the strongest an M2.8 at 29/1607 UTC from Region 4295. No Earth-directed CMEs were observed in available coronagraph imagery. .Forecast... M-class flares (R1-R2/Minor-Moderate) are likely, with a slight chance for an X-class flare (R3-Strong), over 30 Nov-02 Dec. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux reached high levels with a peak flux of 23,004 pfu observed at 29/1640 UTC. The greater than 10 MeV proton flux was at background levels. .Forecast... The greater than 2 MeV electron flux is expected to reach high levels on 29 Nov-02 Dec. The greater than 10 MeV proton flux is expected to remain at background levels through 02 Dec. Solar Wind .24 hr Summary... Solar wind parameters continued to reflect the influence of a positive polarity coronal hole high speed stream. Total magnetic field strength varied between 3-8 nT, and the Bz component reached as far south as -6 nT frequently throughout the reporting period. Solar wind speeds remained elevated, with reported values mostly between 550-650 km/s. Phi angle was predominantly oriented in the positive solar sector. .Forecast... Positive polarity CH HSS influences are expected to wane over 30 Nov, followed by a return to at or near ambient levels over 01-02 Dec. Geospace .24 hr Summary... The geomagnetic field was at quiet to active levels under waning positive polarity CH HSS influences. .Forecast... The geomagnetic field is expected to reach active levels on 30 Nov as positive polarity CH HSS influences gradually wane. Mostly quiet conditions are expected to prevail on 01-02 Dec with the return of an ambient solar wind environment.
