Solar activity was at moderate levels. An M-class (R1-Minor) flare was observed from departed Region 4203 (N11, L=233) as it produced an M1.0 at 29/0416 UTC. The largest and most complex region on the disk remained Region 4197 (S18E03, Ekc/beta-gamma-delta). The region appears to have developed weak delta spots in the trailer section with some new spot development in the central portion of the group. The region produced a few C-class flares. C-class activity was also observed from Region 4199 (N04E18, Cai/beta). New Regions 4205 (N18E67, Hax/alpha) and 4206 (N09E70, Hsx/alpha) were numbered this period. A new area of spots became visible on the NE limb, but was not numbered. The remainder of the active regions were stable. No Earth-directed CMEs were observed in coronagraph imagery. .Forecast... M-class flare activity (R1-R2/Minor-Moderate) is expected, with a slight chance for X-class flares (R3-Strong or greater), through 01 Sep. Energetic Particle .24 hr Summary... The greater than 2 MeV electron flux was at normal to moderate levels. The greater than 10 MeV proton flux continued a slow decline throughout the period, with a peak flux of 4.2 pfu observed at 29/0500 UTC. .Forecast... The greater than 2 MeV electron flux is expected to continue at normal to moderate levels through 01 Sep. The greater than 10 MeV proton flux is expected to continue decreasing towards background levels over 30 Aug-01 Sep. There remains a slight chance for S1 (Minor) solar radiation storm levels through 01 Sep. Solar Wind .24 hr Summary... Solar wind parameters reflected nominal levels. Total magnetic field strength peaked at 7 nT, while the Bz component varied between +6 to -5 nT. Solar wind speeds were steady, averaging ~400 km/s during the period. The phi angle remained in a mostly negative orientation. .Forecast... Mostly nominal solar wind conditions are expected to prevail through 30 Aug. A slight enhancement is likely on 31 Aug to 01 Sep due to the onset of negative polarity CH HSS influences. Geospace .24 hr Summary... The geomagnetic field was quiet. .Forecast... Quiet conditions are expected to prevail through 30 Aug. On 31 Aug to 01 Sep, quiet to unsettled conditions are likely due to the onset of negative CH HSS influences.
