837 FXXX12 KWNP 010031 DAYDIS :Product: Forecast Discussion :Issued: 2026 Nov 01 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 # # Forecast Discussion # Solar Activity .24 hr Summary... Solar activity continued at very low levels. Only minor changes were observed in Regions 4564 (N04E44, Dro/beta) and 4565 (N13E63, Hsx/alpha). 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 03 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 through 02 Nov, with high levels likely by 03 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 reflected the onset of CIR ahead of a positive polarity CH HSS. Total magnetic field strength increased to peak of 12 nT late in the period, with sustained periods of southward Bz reaching as far south as -11 nT. Solar wind speeds increased from ~350 km/s at the beginning of the UT day to between 550-615 km/s by the end of the day. Phi angle was predominantly oriented in the positive solar sector. .Forecast... Enhanced solar wind conditions are likely to continue through 02 Nov due to positive polarity CH HSS influences. A return to mostly nominal conditions is expected over 03 Nov. Geospace .24 hr Summary... The geomagnetic field increased to G2 (Moderate) geomagnetic storm levels due to the onset of a influence form a positive polarity CH HSS. .Forecast... The geomagnetic field is expected to reach G1 (Minor) geomagnetic storm levels on 01 Nov due to continued influence from a positive polarity CH HSS. Quiet to unsettled levels are likely on 02 Nov and quiet conditions are likely on 03 Nov as CH HSS influence wanes.
