Dear Collaborators,

Solar activity has been at moderate-to-low levels. The largest event in the previous 24 hours was an M1.0 flare at 07:50 UT on May 16 from the limb target region. This limb region also produced three ~C5 flares in the period. It has been designated as NOAA 13685 with a beta-gamma/D-type configuration. The Major Flare Watch campaign will continue today with 13685 remaining as the target. Please note that NOAA 13679 (S09E18, beta-gamma/E-type) also produced four ~C4 flares. Further C-class activities are expected with a good chance of M-class flares in the next few days.

The position of NOAA 13685 on May 16 at 23:30 UT is:

S13E64 (-820", -200")
