Solar Activity
Solar activity reached moderate levels (R1/Minor). Region 3932 (S17E42, Ekc/beta-gamma) produced an impulsive M1.1 flare at 22/2049 UTC; the largest event of the period. Development continued among the cluster of active regions in the SE quadrant. No Earth-directed CMEs were detected in available data.
Solar Wind
Solar wind parameters were enhanced this period. Total field reached a peak of 9 nT and Bz varied between +8/-7 nT. Solar wind speeds ranged between ~500-700 km/s through most of the period. Phi angle was 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 was at normal and moderate levels.
