IWLOP #041 – Mare Serenitatis
Nectarian Era impact basin predating Mare Imbrium, filled with Imbrium Era mare material, very titanium rich. It is rich in dorsa and rimae. The second strongest subsurface Mass Concentration (or Mascon) on the near side is centred under the Mare Serenitatis.

R1: Dorsa Smirnov and Dorsa Lister form a partial semi-circle that extended to Bessel and to its north. The structure formed by Dorsa Lister almost looks like a 'ghost crater'.
R2: The area surrounding the Dorsa Aldrovandi from Mons Argaeus to Posidonius and the crater Le Monnier is darker than that of the adjacent mare floor. Its also dark south of Dorsa Lister.
C1: The crater Very appears as a bright spot in the north end of Dorsa Smirnov. Very appears to be on the wall of a 'ghost' crater to its north and is also a darkened area.
C2: Dorsa Nicol heads northward and is perpendicular to the dark area of Rimae Plinius, terminating at Dorsa Lister. Dorsa Azara has a curve NW to SE.
