387 FXXX12 KWNP 141231 DAYDIS :Product: Forecast Discussion :Issued: 2026 Apr 14 1230 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. Plage region 4414 (N15, L=025) produced a C1.2 flare at 13/1137 UTC, the largest of the period. Regions 4415 (S18E05, Hsx/alpha) and 4416 (N19W24, Dsi/beta) exhibited decay while remaining relatively quiet. Region 4418 (S11E07, Cro/beta) underwent minor evolution as it gained additional spots and developed rudimentary penumbra. Region 4419 (N13E71, Cso/beta) was observed on the eastern limb and numbered. The CME observed in GOES CCOR-1 coronagraph imagery beginning at approximately 13/1900 UTC was determined to have originated from beyond the southwestern limb and is thus not Earth-directed. .Forecast... Solar activity is expected to be at low levels, with a slight chance for M-flares (R1-R2/Minor-Moderate) over through 16 Apr. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux was at high levels with a peak flux of 1,650 pfu at 13/1720 UTC. The greater than 10 MeV proton flux was at background levels. .Forecast... The greater than 2 MeV electron flux is likely to reach high levels through 16 Apr. The greater than 10 MeV proton flux is expected to remain at background levels through 16 Apr. Solar Wind .24 hr Summary... Solar wind parameters reflected waning positive polarity coronal hole influences. Total magnetic field averaged near 5 nT and the Bz component was near neutral or northward. Solar wind speeds underwent a gradual decrease from near 500 km/s to near 400 km/s by the end of the period. Phi was in a positive solar sector. .Forecast... Solar wind parameters are expected to remain mildly enhanced through 16 Apr due to tenuous CH HSS influences. Geospace .24 hr Summary... The geomagnetic field was quiet. .Forecast... The geomagnetic field is expected to be at quiet to unsettled levels on 14 Apr. Unsettled to active levels are expected on 15 Apr, with a chance (25%) for isolated G1 (Minor) geomagnetic storming periods, under positive polarity CH HSS effects. Isolated unsettled levels are then expected to continue into 16 Apr.
