AR12792 and AR12793 are just patches of faculae neat the SW limb.
In AR12794, the lone Class-J sunspot is on the lead, followed by faculae.
To the east of AR12794, a small active region has just turned to the frontside. with at least 2 sunspots.
This may be AR12795.
Sunspot count: group=2, sunspot=3, R=23
