It has been a long time since we have 4 active regions on the solar disc.
AR12782 is very close to the SW limb, at (S23W75) and only a thin strip of plages is visible.
AR12783 has undergone much changes in the past few hours. The following group suddenly flare up with intense flares, resulting in the formation of several sunspots. This changes the sunspots to Class-C.
AR12784 is less active and the sunspots are diminishing.
AR12785 is very active with flares and eruptive filaments/jets on the SE limb. A Class-J sunspot is visible.
Sunspot count: group=3, sunspot=10, R=40
