Dear Collaborators,

Solar activity has been at a low level since the last message.
The largest event during the period was a C9.7 flare at 19:40 UT
on July 20 from NOAA 13373. 13373 was also the source of two
low C-class flares. Today the target will switch to 13373 that
retains a beta-gamma/D-type configuration. Yesterday's target
NOAA 13372 (N23W39) only produced a C1.9 flare but was
classified as a beta-gamma/F-type sunspot group again. Please
note that NOAA 13379 (N16E61, beta/F-type) rotates on the
visible disk and has produced a C2.3 flare. This region is showing
mixed polarities in its leading and trailing portions. More C-class
flares are expected in the next 24 hours.

The position of NOAA 13373 on July 21 at 03:30 UT

N08W17 (274", 55")
