Dear Collaborators,

The level of solar activity is extremely low. The visible solar disk
continues to have 3 spotted NOAA regions (12818, 12820, 12821) which
are all in decay phase. NOAA 12820 was the only region that produced
any activity since the last message (a B1.1 flare on 29-Apr-2021 at
13:51 UT) and no change in flaring activity is expected in the next
24-hour period. The Max Millennium Program continues to support the
Parker Solar Probe (PSP) 8th perihelion passage. The target will be
the PSP model-consensus magnetic-footpoint location that has changed
from yesterday's pointing at the edge of the southern polar coronal
hole to a different coronal hole located close to the disk centre.

The approximate position of this region on 29-Apr-2021 at 18:00 UT is:

S17E19 , ( -298", -214" )
