46 - Repsold A The LPIs Hi-Res scan of Lunar Orbiter 4's photograph LOIV-189-h3 shows Repsold and its Concentric Crater Repsold A near the frame's left margin. Repsold A is the 46th item in C.A.Wood's list of Concentric Craters (1978). LO-IV-189H Repsold is the large circular enclosure in the center. Straddling its southwest rim is 44-km Repsold G, through which runs a part of Rimae Repsold. The 9-km concentric crater on the northeast floor of Repsold is Repsold A. Beyond it, outside the main rim is 38-km Repsold B (upper right corner). Maps: (LAC zone 22D1) USGS Digital Atlas. Research: Danny Caes.

Additional CC's

Concentric craters and possible concentric craters, not mentioned in C. A. Wood's original list
  • Several photographs of the moon's far side, made by ZOND 8, show the northern part of the Apollo basin. For example: Frame 41 shows Apollo's north-western part near the frame's upper-right corner (above the black disc with white numbers in it). Above this black disc (about "halfway" between the black disc and the frame's upper margin) at 31° South/ 154° West is a Concentric Crater Research: Danny Caes
  • southwest of Aitken (on the floor of Vertregt), see AS15-P-8859, and AS15-P-8861 (this CC is located near the right margins of both frames). See also AS17-150-22964(because of the high solar illumination in this Hasselblad photograph, the "double walled" appearance of the Concentric Crater is not very distinct). Note that this Concentric Crater is not the same as N°20 in C.A.Wood's list!
    • external image aitkencc.jpg
  • in Bell (Bell E). The LPIs Hi-Res scan of Lunar Orbiter 4's photograph LOIV-196-h3 shows Bell and its Concentric Crater Bell E near the frame's left margin. This Concentric Crater was not catalogued in the list prepared by C.A.Wood (1978). Research: Danny Caes. Maps (LAC zone 54C1) USGS Atlas PDF.

  • Possible Concentric Crater at 17° North/ 77°30' West (only the western part of it shows a "double rim", see LOIV-182-h2) (might be Krafft H, see also Krafft K east of Krafft H).
    • external image kraffthcc.jpg
  • Possible Concentric Crater La Condamine SA, at 57°30' North/ 26°30' West (west of the bright ray-crater La Condamine S). See: LOIV-145-h3. Note also the field of curious twisted arc-shapes in the neighborhood of this possible Concentric Crater.

  • Surveyor 1
    • surveyor-small.jpg
    • The series of images above show examples of several CC lookalikes in the region of the Surveyor 1 site taken by the onboard Lunar Reconnaisance Orbiter (LRO) Camera. NB. This is just one example of where possible CCs may be found from this source -- browse and explore the archives here. Click image for larger view. - JohnMoore2

    • These are concentric craters but not the same size range as what is otherwise referred to as concentric craters on the Moon. Each of these is the result of a single small impact into layered lava flows, with a crater formed in each hard lava surface. The fact that kilometer-size CC form near edges of maria is possible evidence that they too result from impacts into layers. I don't think that is the answer, but it could be. - tychocrater Nov 25, 2009

CC's and handcuff-shaped arcs

  • A curious field of twisted bay- and arc-shapes; "handcuffs" (the remains of small craters and crater-like depressions in the shape of open and closed handcuffs) is noticeable in the part of Mare Frigoris between J. Herschel and La Condamine, and north-northeast of La Condamine.
    There seems to be an abundance of Concentric Craters in regions where this kind of twisted bay- and arc-shapes is scattered all over and in quite large amounts.
    The central section of photograph LO IV-152-H1 and the upper half of photograph LO IV-145-H3 show the field of the twisted bay- and arc-shapes (and Concentric Craters) very well.
