Dear Collaborators,

Solar activity has been at low-to-moderate levels. The largest event
since the last message was an isolated M7.3 flare at 20:33 UT on
May 17 produced by the target region NOAA 13685. 13685 has split
into two regions with the other one numbered as NOAA 13686. 13685
retains a beta-gamma/D-type configuration but increases in the sunspot
area. The Major Flare Watch will continue today with 13685 as the
target, but if possible, please also include 13686 (S07E64, alpha/H-type)
in your field of view. Additional M-class flares including a >M5 flare
are likely in the next 24-48 hours.

The position of NOAA 13685 on May 18 at 03:30 UT is:

S13E48 (-688", -189")
