Solar Activity
Solar activity reached high levels this period. The largest flare of the period was an M7.3/2b at 26/0315 UTC, from Region 3938 (N20E46, Dsi/beta-gamma). Region 3932 (S19W06, Fkc/beta-gamma) was stable, yet inactive. New Region 3939 (S17E67, Cso/beta) was numbered, and 3929 (N15W38, L=194) decayed to plage. The remaining regions were either stable or in decay.
Solar Wind
Solar wind parameters on average slowly decreased throughout the period. Total field was at nominal background levels, with a peak of 5 nT, and Bz varying between -5 and +4 nT. Solar wind speeds started the period around 500 km/s and decreased to around 400 km/s. The phi angle remained predominantly negative.
Energetic Particle
The greater than 10 MeV proton flux remained elevated above background but well below the S1 threshold, mostly due to activity that erupted on the far side of the Sun over 20 Dec. The greater than 2 MeV electron flux reached moderate levels.
