910 FXXX12 KWNP 280031 DAYDIS :Product: Forecast Discussion :Issued: 2024 Jun 28 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. Regions 3719 (S15W39, Cso/beta), 3723 (S19E21, Dao/beta-gamma), 3727 (S18E32, Cso/beta) and 3729 (S03E52, Dai/beta) were responsible for all the C-class flares this period. The largest flare was a C4.8/Sf flare at 27/0428 UTC from Region 3729. Slight decay was observed in Region 3720 (S06W30, Dao/beta), while slight growth was observed in the intermediate spots of Region 3729. Due to the length and magnetic structure of Region 3723, the region was split into two, with the leader portion now Region 3730 (S18E09, Cao/beta). The remaining regions were stable and quiet. A CME was observed off the SW limb beginning near 27/1730 UTC in LASCO C2 imagery. Modelling efforts determined a possible glancing influence late on 01 Jul. .Forecast... M-class flares (R1-R2/Minor-Moderate) are likely on 28-30 Jun due primarily to the flare potential of Regions 3723 and 3729. Energetic Particles .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 28-30 Jun. The greater than 10 MeV proton flux is expected to be at background levels on 28-30 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/-8 nT. Solar wind speed ranged from 315-365 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... 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. Mostly quiet conditions are expected on 30 Jun.
