Background image source
- Arrowhead (see Mons Hansteen).
- Blancani (Van Langren's disallowed name for Flamsteed Rho, etc.).
- B-swirl (a nickname from D.Caes for the B shaped Reiner Gamma type swirl at 7 degrees South/ 54 degrees West).
- Billy (of all lunar formations, the floor of this crater might show the most low-albedo value).
- Burrell (a disallowed name from H.P.Wilkins for an uncertain formation near Hansteen. Could it be the B-swirl mentioned at the top of this list? This is perhaps also the same as J.F.J.Schmidt's Melloni).
- Dorsa Flamsteed P (an unofficial name from D.Caes for the concentric system of wrinkle ridges inside the Flamsteed P ring) (the fork-shaped southern end of Dorsum Suess F north of the Flamsteed P ring seems to be part of the concentric system inside of it).
- Dorsa Rubey
- Dorsum Flamsteed A (an unofficial name from D.Caes for the wrinkle ridge northwest of the bowl-shaped crater Flamsteed A, this could be the northwestern continuation of Dorsa Rubey in Letronne).
- Dorsum Letronne F (an unofficial name from D.Caes for the wrinkle ridge running across the bowl-shaped crater Letronne F, west-northwest of Letronne itself).
- Fat H / Inflated H (two nicknames from D.Caes for a compact cluster of hillocks in the shape of an inflated H, southwest of Hansteen, at: LAT -12.91/ LON -53.95).
- Flamsteed P ring (the large ring north of Flamsteed itself, in which Surveyor 1 made the U.S.'s first soft lunar landing).
- Flamsteed-Billy Basin (unofficial name).
- Flamsteed G group (an unofficial name from D.Caes for the officially unnamed group of hills west of Flamsteed) (more precisely, this is a system of bay shaped crater segments, of which Flamsteed G is the largest one).
- Insula Lea (J.Hewelcke's disallowed name for Letronne Pi, according to E.A.Whitaker at a bright spot).
- Linemannus (Riccioli's disallowed name for Flamsteed Kappa).
- Mare Syrticum (J.Hewelcke's disallowed name for the southwestern "corner" of Oceanus Procellarum).
- Melloni (a disallowed name from J.F.J.Schmidt for an uncertain formation somewhere near Hansteen, see also Burrell of H.P.Wilkins).
- Mons Hansteen (Van Langren's Herlici) (also known as Hansteen Alpha or The Arrowhead).
- Oblong craterlet (a nickname from D.Caes for an egg or rugbyball shaped craterlet west of Letronne F, at LAT: -9.26 / LON: -48.36) (shows something of an oblong central peak too!).
- Oceanus Procellarum (Van Langren's Oceanus Philippicus) (the southern part of it, occupying the upper three-fourths of Chart 40).
- Prom. Henrizi D. Venet (Van Langren's disallowed name for the region at, or slightly west of, Letronne).
- Prom. Salamona (Van Langren's disallowed name for the region at, or near, Hansteen).
- Rima Hansteen
- Surveyor 1 (the U.S.'s first lunar lander, soft-landed on the northeastern part of the floor of the Flamsteed P ring) (Surveyor 1 - America's first soft lunar landing) (see also APOD article The Shadow of Surveyor 1; the 50th anniversary of the soft landing of Surveyor 1 at the Flamsteed P ring).
