Note the shallow half crater at the southern part of Norman's rim. The same kind of appearance (a half crater) is noticeable in Mare Tranquillitatis, at crater Sinas.

Additional Information
- Depth data from Kurt Fisher database
- Westfall, 2000: 2.15 km
- Viscardy, 1985: 2 km
- The shadows in LO-IV-132H are consistent with these depth estimates, probably taken from the LTO. - Jim Mosher

A much larger crater surrounding Norman?
There seems to be a much larger circle-shaped formation which is surrounding Norman, with Norman itself slightly off-center toward the southwestern part of the suspected larger crater's "rim", see SLC-map E5 (System of Lunar Craters, 1966).
Investigation of the WAC Nearside - Big Shadows presentation on the ACT-REACT QUICK MAP (LROC) reveals a rather different appearance of this suspected larger crater. It's just a more-or-less arc shaped section of the eastern continuation of the system of wrinkle ridges officially known as Dorsa Ewing. - DannyCaes Feb 18, 2017
Nomenclature
- Named for Robert Norman (unkn-fl. c. 1590), a British natural scientist.
- This replacement name for a formerly lettered crater was introduced on LTO-75C2 (September, 1974; for which it served as the chart title). It was approved in IAU Transactions XVIB (1976). - Jim Mosher
