535 FXXX02 KWNP 240226 WEKFOR :Product: 27-day Space Weather Forecast :Issued: 2025 Feb 24 0214 UTC # Prepared by the US Dept. of Commerce, NOAA, Space Weather Prediction Center # Product description and SWPC contact on the Web # https://www.swpc.noaa.gov/content/subscription-services # # 27-day Space Weather Forecast # Forecast of Solar and Geomagnetic Activity 24 February - 22 March 2025 Solar activity is expected to range from low to moderate levels throughout the period. R1-R2 (Minor-Moderate) activity is possible at different points throughout the period as active regions grow, evolve, return from the far-side of the Sun. There is a slight chance for R3 or greater events if any of the active regions develop additional complex magnetic structures. There is a slight chance for S1 (Minor) or greater proton events, pending the development and activity of the active regions. The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at normal to moderate levels from 24 Feb-09 Mar and 19-22 Mar. From 10-18 Mar, high levels are likely as recurrent negative polarity coronal holes are expected to move into geoeffective positions. Geomagnetic field activity is expected to be at quiet to unsettled levels on 24 Feb-06 Mar with periodic, weak CH influences. Unsettled to active levels, with isolated G1 (Minor) storming conditions are likely from 07-18 Mar as recurrent negative polarity CHs are expected to be in a geoeffective position. A return to mostly quiet conditions is expected on 19-22 Mar as the CHs move out of a favorable position.
