Dear Collaborators,

Solar activity has been at a very low level. The largest event since the last message was a C2.1 flare at 10:44 UT on July 21 from the target region NOAA 13373. 13373 also produced another C1.4 flare during the period. It has been designated as a beta-gamma-delta/E-type sunspot group. NOAA 13379 (N16E49, beta/F-type) and 13378 (S26W15, beta/C-type) also produced two ~C1 flares. Additional C-class flares are expected in the next 24 hours.
