Summary
Vlacq 53.3°S, 38.8°E
A striking large crater, 89 km in diameter and with a depth of 3 km. The crater floor has a prominent central peak. It is linked to Hommel by a chain of various smaller craters. To the southeast – directly bordering the crater wall – is the large crater Rosenberger (96 km, 55.4°S, 43.1°E).
Pitiscus 50.4°S, 30.9°E
Like Vlacq, also a prominent crater, 82 km in diameter with a flat, lava-flooded crater floor. On the floor lies Pitiscus A (10 km) and superimposed on the western rim is Pitiscus E (13 km).
Hommel 54.7°S, 33.8°E
An ancient, fissured crater, heavily eroded by later impacts, that is 126 km in diameter. It was created in the Pre-Nectarian epoch on the lunar timescale. The crater floor lies 2.8 km below the crater's rim and on the floor and on the western wall there are three large craters, Hommel A, D and C (50 km, 28 km and 53 km, respectively). Hommel is bordered directly to the east by Vlacq and to the north by the large crater Pitiscus.
Hommel, Vlacq and Pitiscus form an interesting group, but because of their limb location are not easy to observe. Observations under favourable libration angles are recommended.
Boguslawsky 72.9°S, 43.2°E
A large crater, with a diameter of 97 km and a depth of 3.4 km, which lies west of Boussingault. The crater walls seem to be eroded, broken down, and not sharply defined, similar to many large craters in the southern highlands.
