Dear Collaborators,

Solar activity remains at an extremely low level. NOAA 12796 completed
its decay to plage since the last message. The spotted region that has
rotated over the South East limb is now designated as NOAA 12797. This
region appears to only have spots in its leading polarity, resulting in
an alpha/H-type sunspot group classification. NOAA 12797 produced low-
level activity with two B-class flares (the largest being a B1.2 flare
on 17-Jan-2021 at 23:54 UT). No change in flaring activity is expected
in the next 24 hours. The Max Millennium Program continues supporting
the coordination of observations for PSP's 7th perihelion passage. The
target continues to follow the model-consensus PSP magnetic-footpoint
that is located in the South West quadrant.

The approximate position of this region on 18-Jan-2021 at 23:00 UT is:

S29W59 , ( 732", -434" )
