Al-Bakri

(formerly Tacquet A)

Lat: 14.33°N, Long: 20.24°E, Diam: 12.21 km, Depth: 1.04 km, Rükl: 35

Dark low-albedo spots and radiating streaks are noticeable on Al-Bakri's bright inner slopes. Apollo 15's orbital ITEK-panoramic frames AS15-P-9888 and AS15-P-9893 show remarkable high-sun close ups of Al-Bakri, looking very much like some kind of bright "lunar ring nebula".

High-albedo craterlet north-northeast of Al-Bakri, with smaller companion (a tiny ray-craterlet) immediately south of the larger one (see LRO's Act-React Quick Map). The floor of the larger high-albedo craterlet looks like some sort of valley. - DannyCaes Jun 9, 2012

South-southwest of Al-Bakri (about halfway between Al-Bakri and the elongated hill unofficially known as the Seagull by the folks of the Hitchhiker's Guide to the Moon), at LAT: 13.95 / LON: 20.05 (2 examples, a large and a small one, the large one has a length of about 600 meters). - DannyCaes Oct 16, 2014
North-northwest of Al-Bakri, at LAT: 14.6680, LON: 20.0460 (diameter about 200 meters). - DannyCaes Oct 16, 2014

Named for Abu Abdullah al-Bakri (1014–1094), a Spanish-Arab geographer and historian. He was born in Huelva, the son of the governor of the province. Al-Bakri spent his entire life in Spain, living in Cordova, and never travelled to the locations of which he wrote.
The name Tacquet A was part of the original IAU nomenclature of Blagg and Müller (Catalog Entry 592). That name was a modification of Menelaus A, the name given to this crater by Mädler.
This replacement name for a formerly lettered crater was provisionally introduced on LTO-60B1 (July, 1974). It was approved in 1976 (IAU Transactions XVIB). - Jim Mosher
Felix Chemla Lamèch once proposed naming this crater Drossos, but that name was not accepted by the I.A.U.. Research: Ewen A. Whitaker and Danny Caes (August 2003, mail correspondence).
A system of two arc-shaped remnants of ghost craters, south-southwest of Al-Bakri, is known as The Seagull, because of its typical shape. Thus nicknamed by David North and Akkana Peck.
Three orbital Hasselblad photographs made during the mission of Apollo 15 show The Seagull in close-up: AS15-92-12540, 12541, and 12542. These three photographs are also online as King Size Hi-Res; in Kipp Teague's Project Apollo Archive (Full Hasselblad magazines). D.Caes research.
