Dear Collaborators,

Solar activity has been at a low-to-moderate level for the past
24 hours. The largest event was an M2.3 flare at 03:38 UT,
happening just now, produced by the limb region NOAA 13683
(S23W89, beta/D-type). This region also produced seven C-class
flares yesterday when it was rotating over the west limb. Another
region NOAA 13679 produced two low M-class flares (an M1.9
at 05/21/19:19 UT and an M1.5 at 05/22/03:02 UT) plus two
C-class flares. Today the target will switch to 13679 as yesterday's
target NOAA 13685 has been flare quiet since the last message.
13679 has a beta-gamma/E-type sunspot group and continues
showing magnetic flux emergence. Further M-class flares are
probable before this region rotates beyond the west limb.

The position of NOAA 13679 on May 22 at 03:30 UT is:

S09W48 (697", -128")
