15 December

Solar activity was low. The largest event of the period was a C2 flare
at 15/0913 UTC which appeared to be associated with a filament eruption
centered near S25W50. Region 1917 (S15W31, Dkc/beta-gamma) continued to
exhibit growth in both area and magnetic complexity throughout the
period. The other regions on the visible disk were either stable or
undergoing slight decay. No Earth-directed coronal mass ejections
(CMEs) were observed.
