954 FXXX12 KWNP 310031 DAYDIS :Product: Forecast Discussion :Issued: 2026 Aug 31 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 was at low levels. Region 4518 (N06W09, Cro/beta) was the only region to exhibit growth. The remaining regions were either stable or in decay. X-ray activity was limited to low-level C-class events. Other activity included a filament eruption in the NE quadrant that began erupting after ~30/0600 UTC. Further coronagraph imagery is needed to analyze the event for an Earth-directed component. .Forecast... Solar activity is expected to reach low levels with a slight chance for M-class (R1-R2/Minor-Moderate) activity over 31 Aug - 02 Sep. 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 at background levels. .Forecast... The greater than 2 MeV electron flux is expected to be at normal to moderate levels on 31 Aug, and increase to high levels on 01-02 Sep. The greater than 10 MeV proton flux is expected to continue at background levels through 02 Sep. Solar Wind .24 hr Summary... Solar wind parameters remained enhanced under continued positive polarity CH HSS influences. Total magnetic field strength reached a peak of 12 nT, while the Bz component reached as far south as -11 nT. Solar wind speeds ranged between ~390-475 km/s. The phi angle was predominately positive. .Forecast... Enhanced solar wind conditions are expected to continue through 31 Aug due to positive polarity CH HSS influences. A return to ambient solar wind conditions is expected by 01 Sep and persist through 02 Sep. Geospace .24 hr Summary... The geomagnetic field reached active levels due to positive polarity CH HSS influences. .Forecast... Active conditions are expected early on 31 Aug due to positive polarity CH HSS influences. Mostly quiet conditions are likely over 01-02 Sep.
