Shallow bowl shaped craters

Shallow bowl shaped craters (on mare regions) are difficult to detect because they don't show up like normal eye catching "deep" craters, however, because of their ghost like appearances on orbital high-resolution photographs (Lunar Orbiter, Zond, Apollo, Lunar Reconnaissance Orbiter, etc...) they attract the attention of those who really explore the lunar surface. A typical example (of a shallow bowl shaped crater) is Finsch in Mare Serenitatis (such craters show sharp looking and perfectly circle shaped rims, but... almost no depth in their floors, which means: the sun must shine upon them from very low above the horizon if we want to catch their presence).

List of shallow bowl shaped craters:

MARE FRIGORIS
- Two shallow craters south-southwest of Gartner M, see: http://bit.ly/2AhZur0
- Two shallow craters north-northeast of Baily B, see second photograph in LROC article number 732, or: http://bit.ly/2Al73gI
- The shallow crater at LAT: 56.90, LON: 32.89 (southwest of Gartner) (south-southwest of Gartner D', southeast of Gartner F).

MARE IMBRIUM
- The Ring west of Carlini L (see LROC article number 671).
- The shallow crater west of Laplace F (re-discovered by Aleksander Bozic, aka SandiBandi).
- The small shallow crater southeast of Laplace A and north-northwest of Helicon G.
- The small shallow crater at 40°55' North / 28°25' West (about halfway between Promontorium Heraclides and Helicon).
- The shallow crater northwest of Plato E, south of Plato F (discovered by Aleksander Bozic, aka SandiBandi).

MARE SERENITATIS
- Finsch, south-southeast of Sarabhai, see: http://the-moon.us/wiki/Finsch

MARE TRANQUILLITATIS
- Plinius B (about halfway between Plinius and Jansen).
- The unnamed crater near Rima Jansen (about halfway between the large ghost crater Jansen R and bowl shaped crater Jansen L).
- The shallow crater northeast of Zahringer (Taruntius E) (note: the accompanying craterlets Taruntius EA and Taruntius EB, east-southeast of Zahringer, show other letter designations on the LROC's Act-React Quick Map. More precisely, Taruntius EA is called Taruntius S, while Taruntius EB is called... nothing).

OCEANUS PROCELLARUM
- The small shallow crater at LAT: 8.77, LON: -44.96 (northwest of Kepler E).
- The shallow crater about halfway between Herigonius and Euclides C.
- The shallow crater immediately west of Flamsteed F; about halfway between the Flamsteed P ring and Rand McNally's Leon Hills (Wichmann R).
- The shallow crater southwest of Flamsteed M, east of the Flamsteed P ring.
- The shallow crater southeast of Herodotus A, northwest of the pronounced dome Omega. http://bit.ly/2zS3BcU
- The shallow crater on the short wrinkle ridge north-northeast of Lichtenberg A. http://bit.ly/2BTTAKw
- The shallow crater and its small companion north of Nielsen, with larger "plateau"-like ghostcrater east-southeast of it.
- The shallow crater on the unnamed wrinkle ridge immediately west of Hermann R.
- The shallow crater about halfway between the triplet Hermann F-'S-R and Hermann E east of those three.

SCHICKARD
- Two shallow craters on the eastern part of the floor of Schickard. http://bit.ly/2hqkxwM

SINUS IRIDUM
- The shallow crater at LAT 45.00, LON -32.11. Note: this one and several other craters and wrinkle ridges on the floor of Sinus Iridum should get the names of the scientists mentioned in Carl B. Boyer's book The Rainbow; from Myth to Mathematics (because we are at the Bay of Rainbows here!). There's also a small unnamed sinuous rille about one degree east of this shallow crater.

Note: there's also the curious phenomenon of the shallow half crater (or half plateau) which is "hanging" as an appendage (or as a droplet) on the southern part of a pronounced bowl shaped crater
Four examples:

• Norman in Oceanus Procellarum.
• Sinas in Mare Tranquillitatis.
• Eichstadt G, west of Eichstadt.
• Jansen E in Mare Tranquillitatis (at Jansen E, the small half crater is at the northern part of it).
