Dear Collaborators,

The level of solar activity is extremely low. NOAA 12821 has now
rotated over South West limb while NOAA 12818 and 12820 will also
soon rotate over the same limb. NOAA 12820 was the only region to
produce a flare, a single B1.7 on 1-May-2021 at 19:50 UT. There is
no change in flaring activity expected in the next 24-hour period.
The Max Millennium Program continues supporting the Parker Solar
Probe (PSP) 8th perihelion passage by choosing to target the PSP
model-consensus magnetic-footpoint location. PSP has undergone a
heliospheric current sheet crossing since the last message so the
target now changes to the Eastern edge of the Northern hemisphere
low-latitude coronal hole.

The approximate position of this region on 1-May-2021 at 22:00 UT is:

N11W37 , ( 564", 235" )
