2023 November 19 Sun - Solar surface in white-light, with AR13488, AR13489, AR13490 and possible AR1349a.
.
AR13488 shows up at (N31E24). No sunspot is observed, leaving just patches of faculae.
AR13489 shows up at (S15E58). At least 14 sunspots are observed, embedded in faculae. Both leading and following sunspots come with penumbra and split umbra.
AR13490 shows up at (N18E64). At least 11 sunspots are observed, embedded in faculae. All come with penumbra and split umbra. I believe, judging from the huge area and widely spread latitude/longitude, this AR may be composed of 2 or 3 AR's.
Meanwhile, another new AR, possibly AR1349a, shows up at (N10E80). A sunspot with penumbra is observed.
