:Product: Forecast Discussion :Issued: 2026 Apr 08 0030 UTC # Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center # Solar Activity .24 hr Summary... Solar activity was at low levels, with the largest event of the reporting period being a C5.7 at 07/1832 UTC from Region 4409 (N02W57, Eai/beta-gamma), which continued to see development in its intermediary spots. Region 4411 (S06, L=110) decayed to plage. An area of rapid flux emergence appeared just west of Region 4408 (N08W56, Hsx/alpha); subsequent imagery and analysis suggested this was separate from Region 4408 and it was numbered as Region 4413 (N08W60, Cri/beta-gamma). New Region 4414 (N12E76, Hsx/alpha) produced an impulsive C2.4 flare at 07/2320 UTC. The remaining regions on the disk were either stable or in a state of gradual decline. No Earth-directed CMEs were observed in available coronagraph imagery. .Forecast... Solar activity is expected to be at low levels over 08-10 Apr, with a chance (35%) for M-class (R1-R2/Minor-Moderate) flares and a slight chance (10%) for an X-class (R3/Strong or greater) flares, driven primarily by the flare potential of Regions 4409 and 4413. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux was at high levels with a peak flux of 7,358 pfu at 07/1610 UTC. The greater than 10 MeV proton flux was at background levels and exhibiting slight contamination from the high electron levels. .Forecast... The greater than 2 MeV electron flux is expected to continue to reach high levels through 09 Apr, with a drop to moderate on 10 Apr. The greater than 10 MeV proton flux is expected to remain at background levels. Solar Wind .24 hr Summary... Solar wind parameters reflected the transition out of a waning negative polarity CH HSS into nominal conditions. Wind speeds continued to decline from a peak of ~500 km/s to near 400 km/s by the end of the period. A Sector Boundary Crossing was observed for roughly 8 hrs early in the reporting period, as the phi angle shifted from a a predominantly negative (towards) orientation to a more variable but predominantly positive (away) orientation. Total magnetic field (Bt) averaged around 4 nT while the North-South (Bz) component varied between +/- 3 nT. .Forecast... Solar wind parameters are anticipated to return to nominal, quiet-wind state conditions on 08-09 Apr, before becoming enhanced again on 10 Apr due to the anticipated arrival of a CIR ahead of a positive polarity coronal hole high speed stream. Geospace .24 hr Summary... The geomagnetic field was at quiet to unsettled levels under waning negative polarity CH HSS influences. .Forecast... The geomagnetic field is expected to be at mostly quiet levels with isolated unsettled periods for 08-09 Apr as the solar wind environment stabilizes at nominal levels. G1 (Minor) storming conditions are anticipated early on 10 Apr, and potentially very late on 09 Apr, due to the arrival of the aforementioned CIR.
