2022 September 09 Sun - solar active regions in Ca-K, with AR13092, AR13093, AR13094, AR13096, AR13097, AR13098 and possible AR1309a.

The CMOS of my ASI1600MM Pro is too small to cover the whole Sun. In white-light, I use a 0.63 X lens to reduce the image. However, the Lunt Ca-K filter, when combined with the 0.63X lens , will not reach the focus.
AR13092 is located at (S11W28). 1 large sunspot comes with full penumbra and split umbra. It is at the leading end of the plages.
AR13093 is located at (S26W40). Not observed.
AR13094 is located at (N17W00). 1 sunspot is at the leading end of the plages.
AR13095 is located at (S14W88). Nothing is visible.
AR13096 is located at (N16E43). The leading and following sunspots come with penumbra and split umbra, and are embedded in plages.
AR13097 is located at (S12W13). 2 of the sunspots are observed, embedded in an elongated patch of plages. Flare is observed.
AR13098 is located at (N15E16). Several sunspots are
observed, embedded in plages where flares are also observed..
Possible AR1309a is located at (N13E48). 2 sunspots are
observed, embedded in plages.
