:Product: Forecast Discussion :Issued: 2021 Jan 25 0030 UTC # Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center # Solar Activity .24 hr Summary... Solar activity was at very low levels. Both Regions 2797 (S17W16, Hax/alpha) and 2799 (N23W59, Axx/alpha) were stable and inactive. Region 2798 (L=333) decayed to plage. No Earth-directed CMEs were observed during the period. .Forecast... Solar activity is expected to remain at very low levels, with a slight chance for C-class activity, on 25-27 Jan. Energetic Particles .24 hr Summary... The greater than 2 MeV electron flux reached moderate levels and the greater than 10 MeV proton flux was at background values. .Forecast... The greater than 2 MeV electron flux is expected to be at normal to moderate levels while the greater than 10 MeV proton flux is expected to persist at background levels for 25-27 Jan. Solar Wind .24 hr Summary... Solar wind parameters were slightly enhanced. Total magnetic field strength was mostly between 5-8 nT while the Bz component varied between +8 nT to -6 nT. Wind speed varied between about 350 km/s to 400 km/s. Phi was in a predominately positive solar sector through about 24/1415 UTC when an SSBC from positive to negative was observed. Phi remained in a mostly negative orientation thereafter. .Forecast... Enhancements in the field are expected through early on the 26th as an isolated, negative polarity CH moves into a geoeffective position. A gradual return to background conditions is expected by 27 Jan. Geospace .24 hr Summary... The geomagnetic field was at quiet levels. .Forecast... Quiet to unsettled conditions are anticipated through early on 26 Jan due to CH HSS influence. Quiet conditions are expected for the remainder of 26 Jan through 27 Jan.
