075 FXXX02 KWNP 030226 WEKFOR :Product: 27-day Space Weather Forecast :Issued: 2025 Mar 03 0201 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 03 March - 29 March 2025 Solar activity is expected to be at low to moderate levels, with a chance for periodic high levels, throughout the period as returning magnetcially complex regions transit then depart the solar disk on 03 -29 Mar. There is a chance for isolated minor solar radiation storm levels throughout the period if any of the returning/developing magnetically complex regions are active and produce an event. The greater than 2 MeV electron flux at geosynchronous orbit is expected to be normal to moderate levels on 06-09 and 19-28 Mar. High levels are anticipated on 03-05, 10-18, and 29 Mar in response to recurrent CH HSS influence. Geomagnetic field activity is expected to be at quiet to unsettled levels on 03-09, 19-24, and 29 Mar. Active levels are expected on 10-18 and 25-28 Mar with possible G1 conditions on 12-15 Mar, associated with recurrent negative polarity CH HSS influences, and again on 26-27 Mar, associated with recurrent positive polarity CH HSS effects.
