Solar Activity
Solar activity reached moderate levels. Region 3928 (S14W57, Dai/beta-gamma) produced a M1.2 flare at 27/1538 UTC, and Region 3938 (N19E18, Dac/beta-gamma) produced an M3.3 flare at 27/2035 UTC. Region 3932 (S17W37, Dai/beta-gamma) added an M4.5 flare, the largest of the period, at 28/1121 UTC. There was an associated 10cm radio burst with a peak flux of 300 sfu. Region 3936 (N14W23, Ekc/beta-delta) remained the largest and most complex on the visible disk, but exhibited decay in its intermediate spots. Region 3938 displayed slight decay, losing some of its intermediate spots as well. The remaining regions were mostly unchanged.
Solar Wind
Solar wind parameters were at nominal levels. Total field ranged from 1-5 nT and the Bz component fluctuated between +/- 4 nT. Solar wind speeds averaged near 310 km/s. Phi was predominantly negative with 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.
