Description
The smaller of a pair of craters situated to the SW of a bend in the Diophantus Rille. The larger and much more prominent crater 2.5 km to the west is Samir. Although the contours in Topophotomap 39B2/S1 indicate a continuously descending bowl shape with a slightly raised lip, the shadows in the Apollo Metric image suggest Louise has a low central peak. - JimMosher JimMosher

Additional Information
- IAU page: Louise
- Depth data from Kurt Fisher database
- Westfall, 2000: 0.26 km
- In comparison to the current official IAU data listed in the title line, the position and dimensions in the older coordinate system of the topophotomap as read by LTVT were: Lat: 28.473°N, Long: 34.214°W, Diam: 0.7 km. The depth listed in the title line was read from the highest point on the rim to the "lowest" point on the floor (which, as indicated above, may be the summit of a central peak).
- Both Louise and Samir are so small that through Earth-based telescopes what is seen is primarily the dusting of bright ejecta that blankets this area -- most readily visible at high sun angles as in the Apollo metric and Clementine images. It is not entirely clear if the bright ejecta were produced by Louise or Samir, but they seem centered on the latter. - JimMosher JimMosher
- Moore et al, 1980 lists the "small crater between Delisle and Diophantus" as a thermal anomaly crater, implying youthful age - - but which is the anomaly crater, Louise or Samir?

Nomenclature
- Louise is a generic French female name. It is not meant to honor any particular person.
- According to NASA RP-1097, Louise is a Minor Feature whose name was originally intended only for use in connection with Topophotomap 39B2/S1(on which it is plotted).
- In addition to Louise and Samir, the other Minor Features labeled on Topophotomap 39B2/S1 are Isabel and Walter.
- All these names were among the 95 Topophotomap Minor Feature names approved by the IAU in 1976 (IAU Transactions XVIIB).
- Much confusion about Louise exists because in Antonin Rükl's popular Atlas of the Moon only a single crater is plotted at this location, and it is labeled "Louise" with a special arrow pointing to it. Similarly, in the popular Virtual Moon Atlas freeware program, only a single name is given in this region, and that name is "Louise". Rükl's reason for choosing the name Louise is unknown. In all likelihood, the crater he drew and labeled is Samir.
