362 FXXX12 KWNP 311231 DAYDIS :Product: Forecast Discussion :Issued: 2026 Aug 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 was at low levels. X-ray activity was limited to low-level C-class events. Region 4520 (S12W01, Dro/beta) exhibited minor growth, and new Region 4521 (N09E75, Hax/alpha) was numbered. The remaining regions were either stable or in decay. No Earth-directed CMEs were observed in available coronagraph imagery. .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 increased to high levels late this period. 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 31 Aug - 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 mildly enhanced as positive polarity CH HSS influences waned. Total magnetic field strength reached a peak of 6 nT, while the Bz component reached as far south as -6 nT. Solar wind speeds ranged between ~425-500 km/s. The phi angle was predominately positive. .Forecast... Solar wind conditions are expected to return to ambient levels on 31 Aug, and persist through 02 Sep. Geospace .24 hr Summary... The geomagnetic field reached active levels due to waning positive polarity CH HSS influences. .Forecast... Periods of active conditions are expected on 31 Aug as positive polarity CH HSS influences wane. Mostly quiet conditions are likely over 01-02 Sep.
