Solar Activity
Solar activity remained at low levels. Region 4105 (S15E28, Eai/beta-gamma) produced the strongest event of the period, a C4.6 flare at 06/1702 UTC. Newly numbered regions 4108 (S22W10, Bxo/beta) and 4109 (S16E48, beta) remained relatively simple as they slowly developed. No Earth-directed CMEs were observed in available coronagraph imagery.
Solar Wind
Solar wind parameters reflected the onset of a modest transient after 07/0015 UTC. Total magnetic field strength increased to a peak of 11 nT and the Bz component rotated as far south as -10 nT. Solar wind speeds ranged from ~380-425 km/s as the feature moved past Earth.
Energetic Particle
The greater than 2 MeV electron flux reached high levels with a peak flux of 5,178 pfu observed at 06/1615 UTC. The greater than 10 MeV proton flux was near background levels.
