Dear Collaborators,

Solar activity was at a moderate level in the past 24 hours. The largest event was an M3.2 flare at 03:12 UT on July 22 from NOAA 13372. 13372 also produced three C-class flares in the period. This region retains a beta/E-type configuration. The target region NOAA 13373 was the source of an M1.0 flare at 04:12 UT on July 22 and also two C-class flares (C2.3 and C9.9). 13373 has decayed to a beta/E-type region but is still emerging new magnetic fluxes in its leading portion. Today the target will continue on this region. C-class activities are expected with some chance of a low M-class flare in the next 24 hours.
