The active region on the SE limb has partially turned to the frontside. Apart from eruptive flares, a large sunspot has appeared.
This sunspot may be larger than the sunspot of AR12783.
Pay attention to this region.
Meanwhile, both the leading and following sunspots of AR12784 have split into 2.
Sunspot count: group=3, sunspot=6, R=36
