220 FXXX12 KWNP 260031 DAYDIS :Product: Forecast Discussion :Issued: 2026 Oct 26 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 4560 (N13W84, Fao/beta) produced the strongest flare of the period, a C1.5/Sf at 25/1942 UTC. Two regions of emerging flux were observedin the SW and SE quadrant but will need to persist longer before begin assigned an active region number. No Earth-directed CMEs were observed in available coronagraph imagery. .Forecast... Solar activity is likely to remain at very low levels through 28 Oct, with a slight chance for isolated M-class flares (R1-R2, Minor-Moderate) on 26 Oct. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux reached high levels, with a peak flux of 2,864 pfu observed at 25/1820 UTC. The greater than 10 MeV proton flux remained steady at background levels. .Forecast... The greater than 2 MeV electron flux is expected to continue reaching high levels through 28 Oct. The greater than 10 MeV proton flux is anticipated to persist at background levels through 28 Oct. Solar Wind .24 hr Summary... Solar wind parameters continued at nominal levels. Total magnetic field stregnth was at or below 6 nT and no signficant periods of southward Bz were observed. Solar wind speeds varied between ~350-375 km/s. Phi was predominantly oriented in the positive solar sector. .Forecast... Nominal conditions are expected to maintain through 28 Oct. Geospace .24 hr Summary... The geomagnetic activity was at quiet levels. .Forecast... The geomagnetric field is likely to remain at mostly quiet levels over 26-28 Oct.
