LO-IV-079H Chacornac is the 51-km diameter crater above center, with the south rim of Posidonius above it. The arrows indicate the Rima Chacornac I and IV components of Rimae Chacornac as identified in the System of Lunar Craters and on LAC-43. Rima Chacornac I runs just to the west of 5-km Chacornac A (the crater on the floor) and 6-km Chacornac B (the crater on the rim). It terminates near 21-km Le Monnier A (the crater with the fluted rim at the bottom of the frame). Rima Chacornac IV runs from near an unnamed 8-km crater on the south rim of Posidonius to where it disappears into Le Monnier/Mare Serenitatis near 4-km Le Monnier K. The other two classic components of this rille system were Rima Chacornac II, which starts on the floor of Chacornac to the east of Rima Chacornac I; and Rima Chacornac III, which angles to the east of Rima Chacornac I;
outside the crater rim, at about 5 o-clock. Neither of these is easy to spot in this Lunar Orbiter view.

LPOD Photo Gallery Lunar Orbiter Images Apollo Images The system of Rimae Chacornac was captured on Apollo 15's and Apollo 17's oblique north-looking Fairchild Metric-Mapping photographs. Since October 2017 it is possible to get a wonderful simulation of this oblique northward view (of the Posidonius-Chacornac region) in the new version of the LROC Act-React Quick Map (the rotateable digital moon's "3D" sphere).
