Dear Collaborators,

Solar activity continues at a moderate level. The target region NOAA 13712 produced two M-class flares (an M2.4 at 11:14 UT and an M1.2 at 12:11 UT today) and more than ten C-class flares. It retains a beta-gamma-delta/E-type configuration with increasing the sunspot area (to 1100 μh) and number of spots slightly. We will continue the Major Flare Watch campaign on this region. Low M-class activity is expected with a chance of a >M5 flare in the next 1-2 days.

The position of NOAA 13712 on June 18 at 19:30 UT is:

S26W23 (332", -435")
