AR13488 shows up at (N31E10). No sunspot is observed, leaving just patches of faculae.
AR13489 shows up at (S15E45). At least 15 sunspots are observed, embedded in faculae. Most of the sunspots come with penumbra and split umbra.
AR13490 shows up at (N22E62). At least 20 sunspots are observed, embedded in faculae. Most sunspots come with penumbra and split umbra. However, judging from the huge area and widely spread latitude/longitude, this AR may be composed of 2 or 3 AR's.
AR13491, shows up at (N11E68). A sunspot with penumbra is observed.
Meanwhile, a new AR, possibly AR1349a, shows up at (S13E86) and 1 sunspot with penumbra is observed.
