Note the strong hexagonal shape and twin peaks of Chaplygin, and the very sharp looking ray-craterlet Chappy on the northeastern part of Chaplygin's rim (see Additional Information and Nomenclature below).

AS13-62-8909 shows Chaplygin' between Apollo 13's Command Module Odyssey (right) and one of LM Aquariuss antennae (left). Schliemann is the crater below centre. Although Apollo 13 was the most troubled mission of Project Apollo's nine lunar flights, its crew made some spectacular orbital Hasselblad photographs of the moon's cratered Far-Side surface! Image AS13-62-8909 is one of them.

Additional Information
A bright ray-craterlet on the northeastern part of Chaplygin's rim is described and depicted in NASA SP-362, APOLLO OVER THE MOON: A VIEW FROM ORBIT, Chapter 5: Craters (Part 1), Figure 107 (which is a stereo-image of two ITEK-panoramic photographs!).
Note: this is the ray-craterlet unofficially called Chappy by Mark Robinson, see the LROC-page Chappy.
Trivia
What is the out-of-focus object in the centre of orbital Hasselblad image AS10-28-3993 ? (note: this is one of the photographs which is included in the LPI's gazetteer of Chaplygin-Hasselblads). D.Caes research.
Nomenclature
- Chaplygin B was officially approved by the IAU on the 25 July 2017 - JohnMoore2 JohnMoore2
- Named for Sergey Alexeyevich Chaplygin (April 5, 1869 – October 8, 1942), a Russian physicist, mathematician, and mechanical engineer. He is known for mathematical formulas such as Chaplygin's equation. Chaplygin's theories were greatly inspired by N. Ye. Zhukovsky, who founded the Central Institute of aerodynamics. His early research consisted of hydromechanics. His "Collected Works" in four volumes were published in 1948.
- Chaplygin was among the long list of farside names approved by the IAU in 1970 and published in Menzel, 1971.
- In the planning for Apollo 8, the first manned circumlunar mission (1968), this crater (which did not then have an official name) was referred to informally as "Webb", a name which properly refers to a completely different nearside crater (source: Phil Stooke's LPOD).
Chappy on Chaplygin's rim
- Chappy is Mark Robinson's unofficial name for the distinct ray-craterlet on the northeastern part of Chaplygin's rim. See Mark's very interesting LROC-pages Chappy, Chappy Oblique. - DannyCaes DannyCaes Mar 4, 2016
