Details:
AR4168 sets, after 10 days on the face producing ten M flares (some with eruptions, including the one which, through a coronal hole, caused the 24h G1-2 geomag storm). The other gamma, AR4172, is central, grown up but so far emitted C flares only. The SE cloud noted by photographers in reecent days is still there and its base has risen: named AR4179 it has few sunspot content but is continuously bright. The nearby zone behind SE limb is interesting also for a thick loop I luckily catched in timelapse, which appeared and disappeared in 30 minutes, evoling almost in real time, possibly from another notable AR behind SE limb. Long filament activity continues, these days with winding filaments in both hemispheres, the one in N hemisphere being connected to 4172. Lunt60, Neptune-M.
