Solar Activity
Solar activity was low, with only C-class flare activity observed. Most of the flare activity originated from Region 4127 (S20W72, Dai/beta) which saw flux emergence near its trailer spot during the period. Newly numbered Region 4135 (S09E69, Dai/beta) came into view with its magnetic field still being skewed by foreshortening. Remaining active regions were either stable or in decay.
Solar Wind
Solar wind parameters reflected continued but waning influences from a negative polarity CH HSS. The total magnetic field has been trending down from a peak of 14 nT to around 6 nT, the Bz component has been oscillating between +/-5 nT for most of the period. Solar wind speeds have been around 550 km/s with the phi angle being mostly 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.
