2022 January 16 Sun - solar surface in H-alpha, with AR12924, AR12925, AR12927, AR12928, AR12929, AR12930, AR12931, AR12932 and possible AR12933.
.
AR12924 is mostly on the backside, at (S31W91), but some plages are still observed.
AR12926 has turned to the backside.
AR12925 is located at (S34W64) and comes with 1 sunspot, embedded in a long strip of plages.
AR12927 is located at (S21W20). 1 sunspot is visible, with penumbral fibrils and followed by extensive web of plages..
AR12928 is located at (S20W49). No sunspot is visible, leaving just patches of plages.
AR12929 is located at (N09W27). Many sunspots are visible. Both leading and following sunspots come with penumbral fibrils. Flares are observed. Arch filaments connecting magnetic centers are visible.
AR12930 is located at (N21W26). Several sunspots are visible. The following sunspot comes with penumbra. Flares are observed. A huge filament runs from NW to NE, where a huge ensemble of filaments are visible.
AR12931 is located at (N13W61). Several sunspots are visible. The following sunspot comes with penumbra. Flares are observed.
AR12932 is located at (N32E53). Several sunspots are visible. A flare is visible next to the sunspot. It seems some shock wave is produced and propagates eastward.
Meanwhile, possible new AR12933, located at (S21E13). The large sunspot with penumbral fibrils is visible. Flares are observed, so are arch filaments connecting magnetic centers.

Sunspot count: group=8, sunspot=44, R=124
