762 FXXX12 KWNP 271231 DAYDIS :Product: Forecast Discussion :Issued: 2024 Jun 27 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. Regions 3723 (S19E23, Fai/beta-gamma-delta) and 3729 (S03E59, Dai/beta) were responsible for most of the C-class flaring. The largest was a C6.2/Sf flare at 25/1530 UTC from Region 3723. Slight decay was observed in Regions 3723 and 3720 (S06W24, Dao/beta). Slight growth was observed in the intermediate spots of Region 3729. No Earth-directed CMEs were observed. .Forecast... M-class flares (R1-R2/Minor-Moderate) are likely on 27-29 Jun due primarily to the flare potential of Regions 3723 and 3729. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux was at normal to moderate levels and the greater than 10 MeV proton flux was at background levels. .Forecast... The greater than 2 MeV electron flux is expected to be at normal to moderate levels on 27-29 Jun. The greater than 10 MeV proton flux is expected to be at background levels on 27-29 Jun. Solar Wind .24 hr Summary... Solar wind parameters became enhanced after 27/0330 UTC. Total field gradually increased to 13 nT while the Bz component was between +9/-4 nT. Solar wind speed ranged from 330-383 km/s. Phi angle was mostly negative. .Forecast... Solar wind conditions are expected to continue to be enhanced through 27 Jun. An additional enhancement from the large filament eruption observed late on 24 June is likely to arrive late on 28 Jun through 29 Jun. Geospace .24 hr Summary... The geomagnetic field was at quiet to unsettled levels. .Forecast... Quiet to unsettled levels are expected on 27 Jun. Unsettled to G1 (Minor) storming is likely late on 28 Jun through 29 Jun with the arrival of flanking effects from the 24 Jun CME.
