755 FXXX12 KWNP 300031 DAYDIS :Product: Forecast Discussion :Issued: 2026 Jan 30 0030 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. Low level C-class flares were observed from Regions 4353 (N18W82, Bxo/beta) and 4357 (S13W34, Cri/beta). Slight growth was observed in Region 4357. Separation occurred in Region 4349 (S14W60, Hax/alpha). The rest of the spotted Regions were in decay. New Regions 4362 (S17E72, Hax/alpha) and 4363 (S23E74, Hrx/alpha) both rotated into view from the SE limb and were numbered. No Earth-directed CMEs were observed. .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 6,959 pfu observed at 29/1805 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 on 30-31 Jan and 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. Solar wind speed increased from approximately 625 km/s to near 700 km/s. Total field remained steady at about 6-8 nT while the Bz component varied between +/-7 nT. Phi angle was predominantly negative. .Forecast... Enhancements in the solar wind environment are expected on 30-31 Jan under negative polarity CH HSS influences. Geospace .24 hr Summary... The geomagnetic field was at unsettled to active levels due to CH HSS effects. .Forecast... Quiet to unsettled levels, with isolated active periods, are expected on 30-31 Jan as HSS conditions persist. Mostly quiet levels are expected on 01 Feb as CH HSS influence dissipate.
