2020 November 25 Sun - solar surface in white-light, with AR12783, AR12784, AR12785 and AR12786

AR12783 is moving towards the SW limb, at (S20W19). The leading sunspot is still intact, with 2 smaller sunspots to its east. The following sunspots have all reduced to tiny pores.

AR12784 No visible sunspot.

AR12785 is now more distant from AR12786 as the effect of foreshortening diminishes. The sunspot remains the same Class-J.

AR12786 moves away from the SE limb, and the sunspot shows more its structure. The south part of its penumbra is splitting, and it seems the umbra is either splitting or a light-bridge is forming. 2 small following sunspots are visible to the far east of the faculae.
