813 FXXX12 KWNP 031231 DAYDIS :Product: Forecast Discussion :Issued: 2026 Oct 03 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 very low levels. A new region was observed rotating around the Suns E limb and will be assigned an active region number if it persists. The remaining numbered active regions on the visible disk were mostly simple and quiet. No Earth-directed CMEs were observed in coronagraph imagery. .Forecast... Solar activity is expected to be at very low levels, with a chance for C-flares through 05 Oct. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux was at moderate levels. The greater than 10 MeV proton flux continued at background levels. .Forecast... The greater than 2 MeV electron flux is expected to be at normal to moderate levels on 03-05 Oct. The greater than 10 MeV proton flux is expected to remain at background levels through 05 Oct. Solar Wind .24 hr Summary... Solar wind parameters showed a minor enhancement after 03/0118 UTC. Total magnetic field strength increased from ~4 nT to a peak of 9 nT and the Bz component rotated as far south as -6 nT. Solar wind speeds increased from 271 km/s to ~300 km/s. Phi angle was oriented primarily in the negative solar sector. .Forecast... Enhanced solar wind conditions from the influence of a CH HSS are expected over 03-05 Oct. Geospace .24 hr Summary... The geomagnetic field was at quiet to unsettled levels. .Forecast... Active levels on 03 Oct followed by G1 (Minor) storm levels on 04 Oct are likely due to the influence of a coronal hole high-speed stream. Unsettled to active levels are expected to persist into 05 Oct as CH HSS influence wane.
