713 FXXX02 KWNP 020156 WEKFOR :Product: 27-day Space Weather Forecast :Issued: 2026 Mar 02 0144 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 02 March - 28 March 2026 Solar activity is expected to be at low levels, with a change for M-class (R1-R2/Minor-Moderate) flares throughout the outlook period. Elevated probabilities are related to the flare potential of both currently observed spot groups on the visible disk as well as the potential from regions that are expected to return from the Sun's farside. No proton events are expected at geosynchronous orbit. The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 02-08 Mar, 11-12 Mar, 15-19 Mar, and 21-28 Mar due to anticipated influence from multiple, recurrent, CH HSSs. The remainder of the outlook period is likely to be at normal to moderate levels. Geomagnetic field activity is expected to range from quiet to G2 (Moderate) geomagnetic storm levels. G2 conditions are likely on 21 Mar; G1 (Minor) conditions are likely on 22 Mar; active conditions are likely on 03 Mar, 10 Mar, 12 Mar, 14-15 Mar, 20 Mar, and 23-25 Mar; unsettled conditions are likely on 02 Mar, 04 Mar, 06 Mar, 08-09 Mar, 11 Mar, 13 Mar, 16-19 Mar, and 26-28 Mar. All elevated levels of geomagnetic activity are associated with the anticipated influence of multiple, recurrent, CH HSSs. The remainder of the outlook period is likely to be at mostly quiet levels.
