Dear Collaborators,
Solar activity remains at an extremely low level. The small flux region
in the Southern hemisphere that developed pores has now been designated
as NOAA 12796. This region is classified as a beta/C-type sunspot group
and produced an A7.2 flare on 16-Jan-2021 at 10:27 UT. However, 12796
has subsequently shown signs of decay. No change in flaring activity is
expected over the following 24-hour period. The Max Millennium Program
continues to support the coordination of observations for the PSP 7th
perihelion passage. PSP is expected to cross the Heliospheric Current
Sheet (HCS) in the next 6 hours, with its magnetic-footpoint location
jumping to the Southern hemisphere (and also jumping in longitude). As
such, we provide the model-consensus magnetic-footpoint of PSP here for
two separate times (i.e., before and after PSP crosses the HCS).
The approximate position of this region on 16-Jan-2021 at 23:00 UT is:
N32W02 , ( 29", 585" )
then, following the HCS crossing, the approximate position of this
region on 17-Jan-2021 at 06:00 UT is:
S27W35 , ( 500", -383" )
NOTE: PSP is orbiting in the same direction as solar rotation, but at
a faster rate.

Dear Collaborators,
The level of solar activity remains extremely low. One of the weak
flux regions in the Southern hemisphere has developed pores in its
leading and trailing polarities since the last message. However, no
significant flares have occurred. No change in flaring activity is
expected in the next 24 hours. The Max Millennium Program continues
supporting the coordination of observations for the 7th perihelion
passage of PSP that is now at the stage where it's orbiting faster
than solar rotation. The target region follows the model-consensus
magnetic-footpoint of PSP that remains located in the North East
quadrant.
The approximate position of this region on 15-Jan-2021 at 23:00 UT is:
N31E18 , ( -259", 567" )

Dear Collaborators,
Solar activity continues to be at an extremely low level. A different
very small flux region in the South West quadrant has developed a pore
since the last message, but the solar disk is otherwise spotless. No
flares have occurred since the last message, and no change in flaring
activity is expected over the next 24-hour period. The Max Millennium
Program continues to support the coordination of observations for the
PSP 7th perihelion passage through the target region following the PSP
magnetic-footpoint that is located in the North East quadrant.
The approximate position of this region on 14-Jan-2021 at 21:00 UT is:
N32E37 , ( -499", 569" )

Dear Collaborators,
The level of solar activity remains extremely low. The small flux region
in the South East quadrant decayed further in the previous 24 hours, and
produced an A4.4 flare on 13-Jan-2021 at 12:05 UT. There are no spots on
the visible disk, and no change in flaring activity is expected over the
following 24 hours. The Max Millennium Program continues supporting the
coordination of observations for the 7th perihelion passage of PSP, with
today's target tracking its magnetic-footpoint located in the North East
quadrant.
The approximate position of this region on 13-Jan-2021 at 23:00 UT is:
N37E47 , ( -571", 628" )

MM#021 Parker Solar Probe Perihelion Passage
Dear Collaborators,
Solar activity remains at an extremely low level. The very small bipolar
flux region in the South East quadrant has continued to decay since the
last message, with no spots on the visible disk. No flares have occurred
since the last message, and no change in flaring activity is expected in
the next 24-hour period. The Max Millennium Program continues to support
the coordination of observations for the PSP 7th perihelion passage, with
the target continuing to track the PSP model-consensus magnetic-footpoint
in the North East quadrant.
The approximate position of this region on 12-Jan-2021 at 22:30 UT is:
N32E61 , ( -724", 547" )

Dear Collaborators,
The level of solar activity is extremely low. The small bipolar flux region
in the South East quadrant has lost its pore since the last message and the
visible disk is otherwise spotless. No flares have occurred since the last
message and no change in flaring activity is expected over the following 24
hours. The Max Millennium Program continues to support coordination of solar
observations during the 7th perihelion passage of PSP, with today's target
continuing as the model-consensus magnetic-footpoint of PSP that is located
in the North East quadrant.
The approximate position of this region on 11-Jan-2021 at 23:00 UT is:
N28E69 , ( -805", 480" )

Dear Collaborators,
Solar activity continues to be at an extremely low level. A very small bipolar
flux region rotated over the South East limb yesterday and shows a small pore,
but the visible disk is otherwise spotless. No flares have occurred since the
last message and no change in flaring activity is expected in the next 24-hour
period. The Max Millennium Program continues supporting the PSP 7th perihelion
passage by the target remaining as the PSP model-consensus magnetic-footpoint
location in the North East quadrant.
The approximate position of this region on 10-Jan-2021 at 21:00 UT is:
N30E75 , ( -816", 502" )

Dear Collaborators,
The level of solar activity is extremely low. There continue to be no sunspots
on the visible solar disk and STEREO-A images confirm that there are no active
regions situated beyond the Earth-viewed East limb. No significant flares have
occurred since the last message, and no change in flaring activity is expected
in the following 24 hours. The Max Millennium Program continues supporting the
7th perihelion passage of PSP by choosing our target to be the model-consensus
magnetic-footpoint location of PSP, which has recently rotated over the North
East limb.
The approximate position of this region on 9-Jan-2021 at 22:00 UT is:
N35E76 , ( -776", 572" )

Dear Collaborators,
Solar activity remains at an extremely low level. The visible solar disk
is devoid of sunspots, while images from STEREO-A show that there are no
active regions situated beyond the Earth-viewed East limb. No flares have
occurred since the last message, and no change in activity is expected in
the next 24 hours. At this point the Max Millennium target changes focus
to specifically support the 7th perihelion passage of Parker Solar Probe
(PSP encounter 7). The target is the expected magnetic-footpoint location
of PSP that is currently modelled as being located just beyond the North
East limb.
The approximate position of this region on 8-Jan-2021 at 23:00 UT is:
N30E90 , ( -844", 486" )

Dear Collaborators,
The level of solar activity is still extremely low. There continues
to be no sunspots on the visible solar disk. A single A-class flare
has occurred from a small bipolar magnetic flux region in the South
West quadrant, but the target remains with yesterday's filament. No
change in flare activity is expected in the following 24-hour period.
The approximate position of this region on 7-Jan-2021 at 18:30 UT is:
S22W26 , ( 397", -312" )
