27 December


Solar activity remained at low levels. Region 1934 (S16W19,
Cao/beta-gamma) produced two of the three C-class flares during the
period. The first, a C1/Sf, erupted at 27/0938 UTC with the second, a C2
flare, occurring at 27/1122 UTC. Both appeared to originate from the
area near the trailer spots. Region 1936 (S16E25, Dai/beta-gamma)
produced the only other flare of the period, a C1/Sf, that erupted at
27/0734 UTC. Neither appeared to produce associated coronal mass
ejections (CMEs). Region 1931 displayed slight penumbral separation, but
remained stable as it progressed to the west limb. Region 1934
maintained a weak mix of polarities in its trailer portion, but was also
fairly stable throughout the period. Region 1936 also maintained a weak
mix of polarities in its trailer portion, showed spot and penumbral
development early in the period, then developed another spot in the
leader. This region is the spot group of interest and should be
monitored closely. New Region 1938 (S13E68, Hax/alpha) was numbered as a
simple H-type group as it rotated further onto the visible disk over
night. There were no Earth-directed CMEs detected during the period.
