Copernicus's craterlet clusters near Mons La Hire
There's a number of irregularly shaped craterlet clusters in the neighbourhood of Mons La Hire. The origin of most of these clusters is (was) the impact which created crater Copernicus to the south-southeast (each one of these clusters shows its own short "comet's tail", radiating out toward the opposite direction of Copernicus's location). Almost every cluster near Mons La Hire was photographed in close-up during the missions of Apollo 15 and 17. It is a real pleasure to detect all of those clusters on Chart 21 (page 55) in the 21st Century Atlas of the Moon (C.A.Wood/ M.Collins), and in the LPI's online Hasselblad magazines of Apollo 15's orbital photography! - DannyCaes Oct 5, 2013
The LA HIRE C cluster (aka the Chopper)
The location of this cluster (which has a typical Chopper-like shape!) is west of Mons La Hire and southwest of La Hire Alpha (aka Wilkins's Mount Whipple).
Its location on Chart 21 of the 21st Century Atlas of the Moon is G4 (slightly to the left of Mons La Hire).
AS15-92-12452 is perhaps the best one of Apollo 15's close ups of the La Hire C cluster.
AS15-96-13028 shows the La Hire C cluster early in the local morning (shadows in the craterlets).
Apollo 17's AS17-155-23729 and 23730 show the La Hire C cluster from a distance.
Apollo 17's panoramic ITEK-camera frame AS17-P-3101 shows La Hire C near the right margin (scroll all the way to the right).
Lunar Orbiter 4's frame 133-h3 shows the typical Chopper-like shape of the La Hire C cluster (you can't miss it, it's driving to the right, to the east). One might wonder if this cluster's Chopper shape is also noticeable through telescope.

Description
Description: Elger
(IAU Directions) LAHIRE.--A large bright isolated mountain in the Mare Imbrium, N.W. of Lambert, in N. lat. 27 deg., W. long. 25 deg. It is, according to Schroter, nearly 5,000 feet high.
Description: Wikipedia
Additional Information
- Depth data from Kurt Fisher database
- Viscardy, 1985: 1.7 km
- Cherrington, 1969: 0.79 km
- Cherrington's height appears to be in error. LTO-40A4 gives a peak elevation of 7289 m compared to a spot elevation on the mare to the south of 5483 m. This gives 1806 m as a reasonable (but overyly precise) estimate of the peak height. - Jim Mosher
Nomenclature
- Named for Philippe de La Hire (1640-1718), a French mathematician and astronomer who made contributions to calculations of the Moon's orbital motion.
- According to Whitaker (p. 218), this name was introduced by Schröter in the form de la Hire.
- This peak is catalog entry 1396 in the original IAU nomenclature of Blagg and Müller, where it is spelled Lahire and the name is attributed to Mädler.
- The IAU changed the spelling to La Hire in 1961, the name under which it appears on Chart E3 of the System of Lunar CratersQuad Maps.
- This feature is listed as Promontorium La Hire in NASA SP-241.
- It is unclear when it acquired the "Mons" prefix -- the name under which it is listed on LTO-40A4 (1974).
- Wilkins and Moore proposed assigning the name Mount Whipple to the system of hillocks to the west-northwest of Mons La Hire, then known as La Hire Alpha (a former IAU-approved name). The I.A.U. did not accept their proposal, although the name Whipple was later use for a crater near the Moon's north pole.
- Mount Whipple (La Hire Alpha) was probably John Adams Whipple (1822-1891), American inventor and early photographer of the moon (mentioned in the book Epic Moon by Sheehan and Dobbins).- DannyCaes Jun 6, 2014
- AS15-81-10978 is an orbital Hasselblad of the former La Hire Alpha/ Mount Whipple.
- The Chopper is Danny Caes's nickname for the remarkable Chopper shaped cluster of craterlets west of Mons La Hire, officially known as La Hire C.
