203 FXXX12 KWNP 301231 DAYDIS :Product: Forecast Discussion :Issued: 2026 Jan 30 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. Region 4357 (S13W47, Cro/beta) exhibted decay in its intermediate and trailing spots. Regions 4364 (S17W26, Axx/alpha) and 4365 (N28W05, Axx/alpha) were numbered this period and were both the culprits for low level C-class flare activity. A possible new spot near the northeast limb was responsible for low level C-class flare activity as well, but remained unnumbered given a lack of observations. No Earth-directed CMEs were observed in available coronagraph imagery. .Forecast... Solar activity is expected to be low with a slight chance for M-class flares (R1-R2, Minor-Moderate) through 01 Feb. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux reached high levels with a peak flux of 8,020 pfu observed at 30/0005 UTC. The greater than 10 MeV proton flux was below the S1 (Minor) threshold. .Forecast... The greater than 2 MeV electron flux is expected to continue at moderate to high levels through 01 Feb. The greater than 10 MeV proton flux is expected to remain at or near background levels through 01 Feb. Solar Wind .24 hr Summary... Solar wind parameters reflected negative polarity CH HSS conditions. Total field ranged 3-6 nT and the Bz component of the IMF was +/- 5 nT. Solar wind speed decreased from near 700 km/s to just under 550 km/s by the end of the period. Phi was predominantly in a negative (Towards) solar sector. .Forecast... The current solar wind regime is expected to continue through 31 Jan before returning to a more ambient-like state. Geospace .24 hr Summary... The geomagnetic field ranged from quiet to active levels. .Forecast... Quiet to unsettled conditions are expected to continue through 31 Jan under negative polarity CH HSS effects. Mostly quiet conditions are expected to prevail on 01 Feb.
