645 FXXX12 KWNP 231231 DAYDIS :Product: Forecast Discussion :Issued: 2025 Nov 23 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 remained at low levels. Region 4291 (S13E60, Eai/beta), the most complex region on the disk, produced an impulsive C6.3 flare at 22/1900 UTC, the stongest of the period. The remaining numbered active regions were either mostly stable or in gradual decay. No Earth-directed CMEs were noted in available satellite imagery. .Forecast... Solar activity is expected to remain at low levels on 23-25 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, and the greater than 10 MeV proton flux in expected to remain at background levels through 25 Nov. Solar Wind .24 hr Summary... Solar wind parameters were near background levels. Total magnetic field strength was between 1-9 nT. The Bz component reached as far south as -8 nT at 23/1117 UTC. Phi angle suggested the passage of a solar sector boundary crossing around 23/0610 UTC, with the phi angle transitioning from a negative solar sector to positive. .Forecast... Mostly nominal conditions are likely for 23-25 Nov. Geospace .24 hr Summary... The geomagnetic activity was quiet to unsettled. .Forecast... The geomagnetic field is expected to be mostly quiet on 23-25 Nov as nominal solar wind conditions are expected to prevail.
