Left: AS15-M-0580 It appears that the IAU name applies to the entire three-pointed depression seen in the lower part of this image. In this view, Vallis Christel, Vallis Krishna and Rima Sung-Mei should be viewed as IAU-named sub-components. Yoshi appears to be an unrelated impact crater, as is, possibly, the very non-descript Manuel. Dorsum Owen may or may not be related to Aratus CA.

Description
Wikipedia
Additional Information
- IAU page: Aratus CA
- Although Aratus CA is basically a rimless depression, it can be seen as a bright dot when the sun is very low to the west. It would appear that the Sun's setting rays are able to shine down Vallis Christel and strike the east wall of the pit between Vallis Krishna and Rima Sung-Mei. - JimMosher JimMosher
Nomenclature
- This is regarded as a satellite feature and hence is named for the "parent" crater, Aratus, even though it is at a considerable distance and unrelated to it.
- There is considerable confusion regarding the nomenclature of this feature. On several of the DMA-prepared NASA maps it is given the provisional name "Lorca" (used as the title for the Topophotomap sheets), and on two of the LM-series maps this name is even listed as "approved by the IAU". But it appears this is a clerical error and the name Lorca (an apparent reference to the Spanish writer) was never approved. - JimMosher JimMosher
- The naming of sub-components of a named feature is rather unusual.
- Aratus CA is called Krishna on chart 23 in Antonin Rukl's Atlas of the Moon.- DannyCaes DannyCaes May 26, 2010

Bibliography

(Note: Greeley refers to the central pit as "Lorca" -- an impression he probably got from the placement of the label for that unapproved substitute name for Aratus CA on the topographic maps)
