Solar Activity
Solar activity reached moderate levels. Region 3928 (S12W50, Dai/beta-gamma) produced a M1.2 flare at 27/1538 UTC as it underwent decay in its trailing spots. Region 3932 (S17W23, Dac/beta-gamma-delta) was the culprit of a C9.5 flare event at 27/0805 UTC and gained additional spots. Region 3933 (S07W48, Dac/beta-gamma) consolidated its leading spots and Region 3936 (N14W16, Ekc/beta-delta) underwent evolution as it grew in length, gaining additional spots in its intermediate area. Region 3938 (N19E25, Dac/beta-gamma) produced an M3.3 flare at 27/2035 UTC, which was the largest of the period. Regions 3940 (S05E38, Axx/alpha) and 3941 (S05E50, Hax/alpha) were numbered this period, but were otherwise unremarkable.
Solar Wind
Solar wind parameters were at nominal levels. Total field ranged 3-5 nT and the Bz component was +/- 4 nT. Solar wind speeds gradually decreased over the course of the period to near 300 km/s. Phi was predominantly negative while undertaking brief excursions into a positive orientation.
Energetic Particle
The greater than 10 MeV proton flux remained elevated above background but well below the S1 threshold. The greater than 2 MeV electron flux reached moderate levels.
