22 December

Solar activity was moderate. Region 1928 (S18W55, Ekc/beta-gamma)
produced a pair of M1/Sf flares at 22/0811 UTC and 22/0837 UTC, which
were the largest events of the period. Region 1928 remains the largest
and most productive region on the disk. Region 1934 (S15E45,
Dac/beta-gamma) appeared to grow in both size and magnetic complexity
this period and was responsible for a C6/1f flare 22/0932 UTC. The
other regions on the visible disk were stable or in decay. No
Earth-directed coronal mass ejections (CMEs) were observed.
