382 FXXX12 KWNP 241231 DAYDIS :Product: Forecast Discussion :Issued: 2025 Nov 24 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. A double-peak C2.5 flare at 24/0625 UTC was the strongest of the period with contributions from both adjacent Regions 4290 (S11E35, Cso/beta) and 4291 (S16E44, Eai/beta-gamma). Newly numbered Region 4293 (N06E50, Bxo/beta) was relatively simple and quiet. Some minor development was observed around Region 4288 (N17W29, Csp/beta) and Region 4292 (S16E15, Cro/beta). No Earth-directed CMEs were observed in available coronagraph imagery. .Forecast... Solar activity is expected to remain at low levels on 24-26 Nov, with a slight chance for moderate levels (R1-R2/Minor-Moderate) mainly due to the flare potential of Region 4291. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux was at moderate levels. The greater than 10 MeV proton flux was at background levels. .Forecast... The greater than 2 MeV electron flux is expected to remain at moderate levels over 24-26 Nov. The greater than 10 MeV proton flux in expected to remain at background levels through 26 Nov. Solar Wind .24 hr Summary... Solar wind parameters were mildly enhanced, possibly due to a transient feature. Total magnetic field strength averaged near 10 nT and peaked at 15 nT. The Bz component reached as far south as -11 nT at 24/1106 UTC. Solar wind speeds increased over the period, starting at ~400 km/s, with a peak of ~700 km/s observed at 24/1109 UTC. Phi angle was variable. .Forecast... Enhanced conditions are likely to continue over 24 Nov. On 25 Nov, the influence from positive polarity coronal hole is likely to drive observed enhancements the solar wind parameters. These elevated conditions are expected to persist through 26 Nov. Geospace .24 hr Summary... The geomagnetic field reached active levels. .Forecast... The geomagnetic field is expected to continue at unsettled to active levels, with G1 (Minor) geomagnetic storms possible, on 24 Nov. On 25 Nov and through 26 Nov field activity is likely to reach G1 (Minor) geomagnetic storm conditions due primarily to the influence of a positive polarity coronal hole.
