325 FXXX02 KWNP 230156 WEKFOR :Product: 27-day Space Weather Forecast :Issued: 2024 Sep 23 0120 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 23 September - 19 October 2024 Solar activity is expected to range from low to moderate levels throughout the outlook period, with a varying chance for M-class (R1-R2/Minor-Moderate) flares. No proton events are expected at geosynchronous orbit, barring significant flare activity. The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 23-26 Sep and 12-15 Oct, with normal to moderate levels expected for the remainder of the period. Geomagnetic field activity is likely to reach unsettled levels on 25-26 Sep due to positive polarity CH HSS influences. Periods of active conditions are likely on 05-06 Oct due to another positive polarity CH HSS. Periods of active conditions are likely again on 10 Oct, followed by likely periods of G1 (Minor) storming on 11-12 Oct, due to yet another positive polarity CH HSS.
