Solar Activity
Solar activity was at low levels. A C1.3 flare was observed at 25/2112 UTC from Region 4120 (N06W31, Dai/beta-gamma), which was the largest event of the period. Regions 4117 (S14W38, Dso/beta) and 4118 (S12W27, Cai/beta) continued to exhibit decay and were relatively quiet. Region 4122 (N13E48, Bxi/beta) was stable and managed a C1 flare. Region 4120 underwent evolution gaining asymmetric penumbra on its leading spots and developed a gamma magnetic configuration. No Earth-directed CMEs were observed in available coronagraph imagery.
Solar Wind
Solar wind parameters reflected negative polarity CH HSS onset. Total field was elevated between 10-16 nT. The Bz component underwent several deflections at near +/- 10 nT. Solar wind speeds gradually increased from ~420 to ~660 km/s. Phi was predominantly in the negative solar sector.
Energetic Particle
The greater than 2 MeV electron flux reached high levels with a peak flux of 1,260 pfu at 25/1355 UTC. The greater than 10 MeV proton flux was at background levels.
