680 FXXX12 KWNP 311231 DAYDIS :Product: Forecast Discussion :Issued: 2026 Oct 31 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 very low levels. Region 4564 (N04E51, Dro/beta) exhibited minor growth while Region 4565 (N13E70, Hsx/alpha) was stable. No Earth-directed CMEs were observed at the available coronagraph imagery. .Forecast... Solar activity is expected to be at very low levels with a chance for isolated C-class flares through 02 Nov. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux was at normal to moderate levels. The greater than 10 MeV proton flux remained steady at background levels. .Forecast... The greater than 2 MeV electron flux is expected to continue at normal to moderate levels on 31 Oct-02 Nov. The greater than 10 MeV proton flux is anticipated to persist at background levels through 02 Nov. Solar Wind .24 hr Summary... Solar wind parameters were enhanced due to positive polarity CH HSS influence. Total magnetic field strength reached a peak of 11 nT and the Bz component reached as far south as -10 nT. Solar wind speeds increased to a peak of 440 km/s. The phi angle was predominately positive. .Forecast... Enhanced solar wind conditions are likely on 31 Oct-02 Nov due to positive polarity CH HSS influences. Geospace .24 hr Summary... The geomagnetic field was at quiet to active levels due to positive polarity CH HSS influences. .Forecast... The geomagnetic field is likely to reach G1 (Minor) geomagnetic storm levels on 31 Oct-01 Nov due to influence from a positive polarity CH HSS. Quiet to unsettled levels are likely on 02 Nov as CH HSS influence wanes.
