  Pierre Charles Le Monnier - Wikipedia, the free encyclopedia
Le Monnier was born in Paris, where his father Pierre (1675-1757), also an astronomer, was professor of philosophy at the college d'Harcourt.
The liberality of King Louis XV of France, in whose favour Le Monnier stood high, furnished him with the means of procuring the best instruments, many made in Britain.
Le Monnier was admitted in 1739 to the Royal Society, and was one of the one hundred and forty-four original members of the Institute.

 Lunokhod 2 - Wikipedia, the free encyclopedia
At this point the main thrusters shut down and the secondary thrusters ignited, slowing the fall until the lander was 1.5 m (4 ft 11 in) above the surface, where the engine was switched off.
Landing occurred at 23:35 UT in Le Monnier crater at 25.85 degrees N, 30.45 degrees E. The lander carried a bas relief of Lenin and the Soviet coat of arms.
After landing, the Lunokhod 2 took TV images of the surrounding area, then rolled down a ramp to the surface at 01:14 UT on January 16 and took pictures of the Luna 21 lander and landing site.

The few craters that have formed on the subsided surface compare in density to the craters formed on the cluster (arrow) of Aristarchus secondary impact craters and associated herring- bone ridges; comparable ages for the Aristarchus secondary features and the depression are thus indicated.
The terrace at the base of the crater walls could be debris from the walls or a "bathtub ring" left by a formerly higher stand of the mare fill.
Craters containing bulbous material (arrows 2) that may be lavas extruded through the brecciated crater floor are visible.

 PIERRE CHARLES LE MONNIER FACTS AND INFORMATION   (Site not responding. Last check: 2007-10-26)
He was born in Paris, where his father Pierre (1675-1757), also an astronomer, was professor of philosophy at the college d'Harcourt.
Le Monnier's first recorded astronomical observation was made before he was sixteen, and the presentation of an elaborate lunar map resulted in his admission to the Academy, on April 21 1736, aged only twenty.
He was chosen in the same year to accompany Pierre Louis Maupertuis and Alexis Clairault on their geodetical expedition to Lapland.

IAU spelling changes pre 1982 8 craters whose spelling was changed prior to AW82 by the IAU but for which the changes were rejected by AW82 on the grounds that the older versions were more familiar and established in the literature.
Note that the crater Greaves appears in AW82 under its correct name and also under its old name of Lick D. For non-craters, I have adopted the traditional nomenclature of AW82 in which the "Mons" is omitted for mountains Pico, Piton, R:umker, Gruithuisen Gamma/Delta, Hadley Delta, rather than the IAU version with Mons added.
For the farside craters, lettered and otherwise, someone needs to go through the early farside maps and catalogs and identify the current names with early designations to see when features were first identified.

We know, both by tradition and published records, that from the earliest times the faint grey and light spots which diversify the face of our satellite excited the wonder and stimulated the curiosity of mankind, giving rise to suppositions more or less crude and erroneous as to their actual nature and significance.
The Taurus Mountains extend from the west side of the Mare Serenitatis, near Le Monnier and Littrow, in a north-westerly direction towards Geminus and Berselius, bordering the west side of the Lacus Somniorum.

 Serviss - The Wrecking of the Moon   (Site not responding. Last check: 2007-10-26)
The lunar craters differ from those of the earth more fundamentally than in the matter of mere size; they are not situated on the tops of mountains.
But everywhere the true craters are in evidence, even on the sea-beds, although they attain their greatest number and size on those parts of the moon--covering sixty per cent of its visible surface--which are distinctly mountainous in character and which constitute its most brilliant portions.
The mighty craters have broken forth one after another, each rending its predecessor; and when their work was finished, a minor but yet tremendous outbreak occurred, and the face of the moon was gored and punctured with thousands of smaller craters.

Smaller crater Burg (39.6 km) to the north more is still barely visible at the terminator’s edge, while the craters of Aristotle and Eudoxus have shaded interior west walls.
Crater Plinius (43.2 km) just off the south edge of Mare Serenity is largely a dark “inkwell,” with only its east interior wall and rim catching sunlight.
Of the crater trio Theophilus, Cyrillus, and Catherina, the first of these appears deepest with the most relief, being almost 1/2 shaded within too.

The northen-most crater in the picture is Daniell, an eliptical crater, 31 by 24 Km across and over 2000 metres deep.
The large crater south of this is Posidonius (95 Km in diameter); it is often referred to as a 'walled plain' and it certainly looks like a crater that has been filled with lava from Mare Serentitatis.
Just to the south is Le Monnier which is about 3,800 million years old and has evidently been flooded by lava.

Serenitatis is a good place for a lunar diameter sequence because it is a relatively uncomplicated surface with a small number of pristine craters that can be confidently identified with a little care.

The same can be said of nearby Le Monnier, but its floor is a deep gray, opening to the west into Mare Serenity.
Plinius at the south side of the Mare is almost 1/2 shaded within, with a central peak catching sunlight — very analogous to the crater Theophilus.

The crater is somewhat over four thousand feet in diameter, and the surrounding rim, formed of upturned strata and ejected rock fragments, rises at its highest point one hundred and sixty feet above the plain.
This remarkable crater is one of the most interesting places in the world, for there is absolutely no record of such a mass, possibly an iron-headed comet, from outer space having come into collision with our earth.
But everywhere the true craters are in evidence, even on the sea-beds, although they attain their greatest number and size on those parts of the moon -- covering sixty per cent of its visible surface -- which are distinctly mountainous in character and which constitute its most brilliant portions.

 Hitchhiker's Guide to Rukl Chart 25   (Site not responding. Last check: 2007-10-26)
South of Le Monnier, something caught my eye: a small crater with a white halo had a sort of slight, miniature rille crossing it much the same way Hyginus rille does on a much larger scale.
It appears to be exactly where Littrow B (now, I think, called Clerke) sits, but the rille structure on the charts only looks sort of like what I saw, and both maps indicate fairly slight rilles there, rather than the more distinct traces I saw.
This may simply be a case of the light bringing out contrast that is not usually there (much like the little craters in Plato last month); once again, we see these odd Transient Lunar Views that show up from time to time, making the whole moon new all over again...
