Solar Activity
Solar activity was at low levels. The region with the most flaring was Region 4105 (S15W04, Eai/beta-gamma) which produced only B- and C-class flares. Region 4107 (S18W31, Axx/alpha) is in decay with other regions remaining stable. No Earth-directed CMEs were observed in available coronagraph imagery.
Solar Wind
Solar wind parameters remained enhanced due to a likely CME arrival from Friday and the continued geoeffective position of the negative polarity CH HSS in the southern hemisphere. Total field was 10-12 nT with the Bz component oscillating between +/-5 nT. Solar wind speeds remained between 450-500 km/s. The phi angle was variable, mostly in the negative.
Energetic Particle
The greater than 2 MeV electron flux was at moderate levels. The greater than 10 MeV proton flux was at background levels.
