Dear Collaborators,

The level of solar activity is medium-to-high. The magnetic flux region
that had begun rotating over the North East limb yesterday now displays
a mature leading spot with penumbra and a small opposite-polarity spot
slightly South East of the main spot (but with disconnected penumbrae,
so not a delta configuration). This region is expected to be designated
as NOAA 12822 at the end of the UT day and it has continued to produce
B-class flares since the last message as well as an M3.9 on 7-May-2021
at 18:43 UT. At this point the Max Millennium Program prematurely ends
its support of the Parker Solar Probe 8th perihelion passage and moves
straight into an MM#003 Major Flare Watch due to the region's potential
to produce an M5 or greater flare. C-class flare activity is expected
in the next 24 hours, with a good chance for another M-class flare.

The approximate position of this region on 7-May-2021 at 21:00 UT is:

N18E74 , ( -870", 308" )
