  • Frame 3213, made by Lunar Orbiter 3, shows an oblique view of Damoiseau and the bay-like crater Damoiseau H.
  • The Hi-Res scan of Lunar Orbiter 4's photograph LOIV-156-h3 shows the concentric crater Damoiseau BA, the 38th item in C. A. Wood's 1978 list of concentric craters, near the frame's lower left corner. This concentric crater is also noticeable near the lower right corner of LOIV-161-h3. Damoiseau D, on the western part of Damoiseau A's rim (southwest of Damoiseau itself), is perhaps also a concentric crater.

(IAU Directions) DAMOISEAU.--Consists of a complex arrangement of rings, an enclosure 23 miles in diameter, with a somewhat smaller enclosure placed excentrically within it (the N. side of both abutting on a bright plateau), with two large depressions intervening between their E. borders. This peculiarity, almost unique, renders the formation an especially interesting object. Damoiseau is situated on the E. side of Grimaldi, on the W. coast-line of the Oceanus Procellarum, from which the S.E. border rises at a gentle inclination. On the N.E. there is a curious curved inflexion of the Mare, bounded by a bright cliff, representing probably the W. side of a destroyed ring, a supposition which is strengthened by the existence of a faint scar on the surface of the sea, extending in a curve from one extremity of the bay to the other, and thus indicating the position of the remainder of the ring. A conspicuous little crater stands at the S. end of it, and two others some distance to the E. The smaller component of Damoiseau contains a low central ridge.



Additional Information


The Damoiseau G ring

  • Damoiseau G ring or Dorsa Damoiseau G are unofficial names from D.Caes for the more-or-less circle shaped system of wrinkle ridges between Damoiseau E (at southwest), Damoiseau G (at northeast), Damoiseau Ga (at southeast), and Damoiseau Gb (at northwest). The centre of this curious ring of wrinkle ridges is the location of a very small hillock which is nicknamed Tiny island by D.Caes. Could this be the uppermost summit of the pronounced central peak of a vanished large crater, of which only some ghost-like appearance of its upper rim remained? - DannyCaes Nov 22, 2015

A tiny island in the southwestern part of Oceanus Procellarum

  • Tiny island (a nickname from D.Caes for the very small (officially unnamed) hillock in the centre of the more-or-less circle shaped system of wrinkle ridges between Damoiseau E and Damoiseau G) (this tiny island is the "chief" of a small cluster of very tiny hillocks) (this cluster is an interesting target for today's telescopic photographers of the southwestern part of Oceanus Procellarum).
  • The LROC's WAC mosaic of albedo formations (the moon "without shadows") shows the Tiny island as a white spot on dark background. I wonder if there are other orbital photographs of that white hillock, for example by the Japanese Kaguya orbiter... (- DannyCaes Nov 22, 2015).

  • Rimae Damoiseau (an unofficial name from a certain dedicated moon explorer for the system of rilles on the floor of Damoiseau).
