Dear Collaborators,

NOAA 12898 has completely rotated over the west limb. Today the
target will switch to NOAA 12904, the only region with sunspots on
the visible solar disk at present. 12904 has a beta/D-type configuration
and produced a C1.3 flare at 12/06/06:50 UT and also a B9.6 flare in
the past 24 hours. 12904 appears to enter its decay phase. B-class
activities are probable in the next 24 hours.

The position of NOAA 12904 on December 7 at 04:30 UT is:

S27E26 (-381", -444")
