- Apollo 15's orbital B-and-W Hasselblad AS15-95-12870 doesn't show Rima Sharp (as mentioned in the caption), it shows a northward looking oblique view of Rima Mairan.
- The last frames of Apollo 15's color-Hasselblad magazine 93-P show Rima Mairan as seen from an orbital location slightly southward of it (looking "up north", toward the northern horizon). Of these, AS15-93-12733 shows Rima Mairan near the centre of the frame, with the curious volcanic hillock Mairan T near the upper margin.

  • Named after the nearby crater. (Mairan)
  • Number 85 in Debra Hurwitz's Atlas and Catalog of Sinuous Rilles (together with Rima Sharp).
  • This feature was not depicted on the System of Lunar Craters Quad Maps, and it is depicted but not named on LAC-23. It is not known precisely when or where the present name was introduced (the IAU Planetary Gazetteer gives LAC-23 as the map reference), but it was approved "as assigned" by the IAU in 1985 (IAU Transactions XIXB).
