Additional Information

The centre of this basin seems to be Lacus Luxuriae.


Basins filled with maria are named for the mare, and basins that were previously recognized as craters still bear the crater name. Basins located between craters have the names of the two opposite craters with a hyphen in between, in this case Freundlich and Sharonov.
The name Freundlich-Sharonov Basin seems to be a rather difficult one to write, because it is mentioned (several times) as Freundlich-Sharanov Basin in Charles J. Byrne's The Far Side of the Moon: a Photographic Guide (Springer, 2008).
