Additional Information

  • A somewhat fork- or branch-shaped rille at 6°20' South/ 24°30' East (between Theophilus and Hypatia, in Sinus Asperitatis), is described and depicted in NASA SP-362, APOLLO OVER THE MOON; A VIEW FROM ORBIT, Chapter 5: Craters (Part 3), Figure 136. Detection of this rille's exact location: Danny Caes.


  • The IAU name is Latin for "Bay of Roughness".
  • This name was not part of the original IAU nomenclature. It is one of the 120 names on LTO charts approved by the IAU in 1976
  • Perhaps interesting to add something in here about a certain terrestrial cloud formation called Asperitas, and also about one of the early observers and photographers of this cloud formation: Margaret Anne LeMone
