Dear Collaborators,

Solar activity was at a moderate level in the past 24 hours. The largest event was an M3.8 at 07/19/17:04 UT from yesterday's target NOAA 13363. 13363 also produced another M1.4 flare at 07/19/10:49 UT and more than ten C-class flares. 13363 has completely rotated beyond the west limb and now we end the Major Flare Watch campaign. Today the target will switch to NOAA 13372 that has a beta/F-type configuration. 13372 produced a C2.5 flare yesterday and is showing mixed polarities in its trailing portion. In addition, NOAA 13376 (N25E14, beta/D-type) produced two C2.6 flares during the period. Further C-class activities are expected in the next 24 hours.

The position of NOAA 13372 on July 20 at 03:30 UT

N24W26 (379", 319")
