Solar Activity
Solar activity reached moderate levels due to an M1.4 flare at 03/1303 UTC from newly numbered Region 4105 (S14E64, Dai/beta). The majority of the C-class flares were attributable to this region, however it currently is too close to the E limb for accurate spot/magnetic classification. Slight Decay was observed in Regions 4099 (S14W57, Dai/beta) and 4100 (N10W48, Eki/beta-gamma).
Solar Wind
Solar wind parameters remained enhanced with declining CME effects and CH HSS influences. Total field was generally between 5 to 9 nT. The Bz component was variable with a few brief southward deflections. Solar wind speed averaged near 550 km/s. Phi angle was mostly negative.
Energetic Particle
The greater than 2 MeV electron flux was at moderate to high levels with a peak flux of 3,370 pfu at 03/0355 UTC. The greater than 10 MeV proton flux declined from approximately 3 pfu to near 1 pfu, well below the S1 (Minor) threshold.
