Solar Activity
Solar activity was at low levels with weak C-class flare activity observed. Regions 4127 (S19W59, Dai/beta) and 4134 (S23W15, Dao/beta) indicated intermediate spot growth. Slight growth was observed in the leader portion of Region 4130 (S11W11, Dai/beta). The remaining active regions on the visible disk were either stable or in decay. No Earth-directed CMEs were observed in available coronagraph imagery.
Solar Wind
Solar wind parameters reflected continued negative polarity coronal hole influence during the period. The total magnetic field strength reached 13 nT and the Bz component reached as far south as -10 nT. Solar wind speeds began the period at about 475 km/s, but slowly decreased to end-of-period speeds near 430 km/s. The phi angle was predominately negative.
Energetic Particle
The greater than 2 MeV electron flux was at normal to moderate levels. The greater than 10 MeV proton flux was at background levels.
