481 FXXX12 KWNP 151231 DAYDIS :Product: Forecast Discussion :Issued: 2024 Jul 15 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 reached moderate levels, with Region 3738 (S09W60, Fkc/beta-gamma-delta) continuing to produce M-class activity. The largest flare produced was an M2.7 at 15/0937 UTC. The region remained the most complex on the visible disk. Minor development was observed in its leader and intermediate spots. Region 3752 (N22E60, Hax/alpha) was numbered as it rotated onto the disk from the NE limb. New Region 3753 was numbered near N10W12. Regions 3743 (S08W02, Dai/beta) and 3744 (N15E06, Dso/beta) both underwent minor growth. The remaining numbered active regions on the disk were either mostly stable or in gradual decay. No Earth-directed CMEs were observed in available coronagraph imagery. .Forecast... Solar activity is likely to reach moderate levels (R1-R1/Minor-Moderate), with a slight chance for R3 (Strong), over 15-17 Jul. 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 steady at background levels. .Forecast... The greater than 2 MeV electron flux is expected to be at normal to moderate levels over 15-17 Jul. There is a slight chance for an enhancement of the greater than 10 MeV proton flux at S1 (Minor) storm levels over 15-17 Jul due to the location and flare potential of Region 3738. Solar Wind .24 hr Summary... A nominal solar wind environment prevailed throughout the period. Total field strength ranged from 1-7 nT and no significant periods of southward Bz were observed. Solar wind speeds were slow, being mostly observed between 270-350 km/s. Phi angle was variable. .Forecast... Solar wind parameters are likely to continue at or near nominal conditions from 15-17 Jul. Geospace .24 hr Summary... The geomagnetic field was quiet. .Forecast... The geomagnetic field is likely to continue at quiet levels over 15-17 Jul.
