Dear Collaborators,

Numerous low C-class flares were produced by various active
regions, two by the target NOAA 12911 (beta/C-type), one by
12907 (S19E09, beta-gamma/D-type), one by 12908 (S20E27,
beta-gamma/D-type), one by a limb region (S18E89), and five
by 12909 (S21E39, beta/D-type) including the largest one, a
C2.3 at 12/17/12:55 UT. 12911 retains its beta/C-type sunspot
group while increasing the sunspot area. More C-class activities
are expected with a slight chance of an M-class event in the
next 24 hours.

The position of NOAA 12911 on December 18 at 04:30 UT is:

N19E51 (-718", 331")
