Solar Activity
Solar activity reached moderate levels. Regions 4099 (S14W64, Dao/beta) and 4100 (N10W54, Eai/beta-gamma) continued to decay with the latter being the culprit for an M1.1 flare at 04/2328 UTC, which was the largest event of the period. New Region 4106 (N12E11, Cro/beta) was numbered.
Solar Wind
Solar wind speed parameters increased over the period. This could either be transient influence or a transition back into the HSS. Solar wind speed increased from approximately 550 km/s to near 810 km/s before decreasing to around 760 km/s. Total field increased to 15 nT at 04/1356 UTC before gradually decreasing to near 9 nT while the Bz component was between +10/-11 nT. Phi angle was mostly negative with several deviations into a positive sector.
Energetic Particle
The greater than 2 MeV electron flux reached moderate to high levels with a peak flux of 3,970 pfu at 04/1340 UTC. The greater than 10 MeV proton flux continued to decline towards background levels.
