The CAES catalog of unique and odd lunar surface formations on the moon's near side and libration zones

(observable through common and/or powerful telescopes)


Compiled by Danny Caes (°28-2-1964, Ghent-Belgium)

Introduction

Antonin Rukl, the creator of the legendary Atlas of the Moon made exceptionally fine drawings of the moon's telescopically observable surface. Each one of his 76 maps (of the moon's near side) show details which are worthwile to observe through all sorts of telescopes.
Here, in this page, you see a catalog of very odd lunar surface formations of which most of them are, under stable sky, observable through common and powerful telescopes. Most of these odd formations are described and depicted in scientific magazines and books, but very vaguely mentioned in lunar atlases such as Antonin Rukl's. This catalog is a guide for all the dedicated lunar observers who want to know what's "beyond the commonly known craters" (a survey of less-known surface formations).
Many of the described formations in the CAES catalog are also detectable on the photographic charts of C.A.Wood's and M.Collins's 21st Century Atlas of the Moon. Some of the very small formations require a magnifying glass.
Other VERY important online guides are NASA SP-362 Apollo Over The Moon; a view from orbit, and Apollo 15 Flight Journal; both full of investigations of weird-looking lunar surface formations.
Also extremely important is the ASU's Apollo Image Archive, which has a large collection of zoom-able Mapping/Metric photographs made by the Fairchild cameras aboard the SIM-bays of Apollo 15, 16, and 17 (ideal to create 3D-STEREO images via parallel vision!).

Warning:
The CAES catalog does not contain clair-obscur phenomena which are only observable during local sunrise or sunset (morning- and evening-terminator).
On the other hand, lots of Full-Moon related telescopic targets (albedo-phenomena and subtle colors) are included!

- "Fracastorius's Trifid" on the northeastern part of Fracastorius's rim (a system of three slightly overlapping bay-shaped craterlets).

Map 59: Petavius

Map 60: Vendelinus

Map 61: Piazzi
- Concentric Crater (CC) at 33° South/ 62°20' West (Lagrange T); see IV-160-H3.
- Dark halo craterlet north-northeast of Inghirami; see LAC 109 in B.Bussey's and P.Spudis's Clementine Atlas.

Map 62: Schickard
- Unnamed dark "V"-figure (an unnamed lacus) at 37°South/ 35° West.

Map 63: Capuanus
- Concentric Crater (CC) Marth. Although... it is not sure if this crater is a real CC.
- Bright craterlet ("white spot") in Mee (see LAC 111 in B.Bussey's and P.Spudis's Clementine Atlas).
- "N"-shaped system of rilles just north of Ramsden, see LPOD More Rilles. A curious target for telescope operators at public observatories!

Map 64: Tycho
- Concentric Crater (CC) Hesiodus A, which is the most telescope-friendly one of all the Concentric Craters on the moon's near side.
- Craterlet with double rim in Street M.
- Bright craterlet at 32° South/ 16° West (west of Wurzelbauer D, aka Wilkins's Hauet).
- Bright hill-like (and somewhat cylindrical shaped) surface feature on the western inner slope of Pictet. See LPOD What Do You See? and discussions, and Pictet Puzzle

Map 65: Walther (in Rukl's original atlas mentioned as Walter without h).
- "Horizontal" tendency of repeating depressions arranged as "lines"; on the northern inner slope of Maginus. See LPOD What Do You See? and discussions.

Map 66: Maurolycus
- Bright craterlet Buch B.

Map 67: Rabbi Levi
- Bright crater Nicolai A.
- Lockyer G: pronounced central peak.

Map 68: Rheita
- Ladder-like appearance of Fabricius's central peak.
- Greenish coloration in Young? (see also Part 1 of Colored Regions).
- "Rupes Recta"-like scarp at 33° South/ 44° East (east-southeast of Neander).
- Janssen K's flat floor.

Map 69: Furnerius
- Stevinus A (bright ray-craterlet, very high-albedo!).
- Marinus E (bright crater).

Map 70: Phocylides
- Cluster of bright craters at 50° South/ 73° West (see LAC 124). Called the Inghirami cluster by D.Caes.

Map 71: Schiller
- Bright craterlet at 53°30' South/ 28° West.

Map 72: Clavius
- Triplet in Clavius (59°20' South/ 17° West).
- Doublet in Clavius (59°30' South/ 18°40' West).
- Curious "wafer"-structure at 52° South/ 22° West (on the southern rim of Longomontanus).

Map 73: Moretus
- "Vivid Green" on the southern rim of Maginus? (see also Part 1 of Colored Regions).
- Visibility of the Earth-faced part of the Southpole-Aitken basin near and at the Leibnitz Mountains?
- Lilius Alpha; the pronounced central peak of Lilius.
- Two bowl-shaped high albedo craters called Simpelius G and Simpelius J (at approximately 76 degrees south/ 7 degrees east) are quite interesting targets during Full Moon, because they (both craters) act like "pointers" to get the location of the moon's South Pole (they are a bit like the celestial "pointers" in the well-known asterism Big Dipper of the constellation Ursa Major; to get the location of Polaris, the northern pole star).

Map 74: Manzinus
- Amundsen/Ganswindt basin (is it observable through telescope during very favourable libration?).

Map 75: Hagecius

Limb/Libration regions in the MISCELLANY pages

One of the most dedicated contributors of the Moon-Wiki, John Moore, created (and added) interesting looks at (and investigations of) several of the moon's limb regions in his MISCELLANY pages (an appendix to the daily LPODs):
- First page: Miscellany 1
- Second page: Miscellany 2
- Third page: Miscellany 3
