455 FXXX12 KWNP 240031 DAYDIS :Product: Forecast Discussion :Issued: 2026 Aug 24 0030 UTC # Prepared by the US Dept. of Commerce, NOAA, Space Weather Prediction Center # Product description and SWPC contact on the Web # http://www.swpc.noaa.gov/wwire.html # # Forecast Discussion # Solar Activity .24 hr Summary... Solar activity was at low levels. Region 4513 (N04E25, Ekc/beta-gamma) produced a C4.1/Sf at 23/0653 UTC, the strongest of the period. Only minor changes were observed in the region over the past 24 hours. Region 4517 (N10E11, Dao/beta) exhibited growth in its leader and trailer spots. No Earth-directed CMEs were detected in available coronagraph imagery. .Forecast... Solar activity is expected to be at low levels, with a chance for M-flares (R1-R2/Minor-Moderate) and a slight chance for an X-flare (R3/Strong or greater) over 24-26 Aug. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux reached high levels. The greater than 10 MeV proton flux remained elevated, but below S1 (Minor) levels, ranging from 2-5 pfu throughout the period. .Forecast... The greater than 2 MeV electron flux is expected to reach high levels on 24-26 Aug. There is a slight chance for the greater than 10 MeV proton flux to reach S1 (Minor) levels over 24-26 Aug. Solar Wind .24 hr Summary... The solar wind environment remained at background levels. Total magnetic field strength was at or below 5 nT. No significant periods of southward Bz were observed. Solar wind speeds were between 385-455 km/s throughout the period. The phi angle was predominately negative. .Forecast... Background solar wind conditions are expected to prevail over 24-26 Aug. Geospace .24 hr Summary... The geomagnetic field was at quiet levels under an ambient solar wind environment. .Forecast... The geomagnetic field is expected to continue at mostly quiet levels over 24-26 Aug.
