Solar Activity
Solar activity reached moderate levels this period. Region 3932 (S17E20, Fkc/beta-gamma-delta) produced two M4 flares at 24/0019 and 24/0841 UTC. Development continued among the cluster of active regions in the SE quadrant, with a few small delta spots emerging.
Solar Wind
Solar wind parameters remained enhanced this period. Total field reached a peak of 7 nT and Bz varied between +/- 6 nT Solar wind speeds averaged ~575 km/s, and 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 crossed the alert threshold at 23/1520 UTC, with a peak flux of 1540 pfu at 23/1725 UTC.
