Nearside Named Features

  • Brisbane
  • Claramontius (Riccioli's disallowed name for a low-albedo region, perhaps Mare Australe?).
  • Dorsum Brisbane H (an unofficial name from D.Caes for the wrinkle ridge south-southeast of Brisbane H).
  • Dorsum Brisbane Z (an unofficial name from D.Caes for the wrinkle ridge running across the floor of Brisbane Z, aka Oris).
  • Hanno
  • Lyot
  • Oris (an unofficial name for Brisbane Z, see Additional Information below).
  • Petrov
  • Pontécoulant
  • Pratdesaba (a disallowed name from H.P.Wilkins for Brisbane G, although several sources say it was Lyot).
  • Steinheil (Van Langren's Zamosci, together with Watt).
  • Terra Fertilitatis (Riccioli's discontinued name for the whole of Chart 76).
  • Vallis Brisbane Z (an unofficial name from D.Caes for the pronounced groove immediately south of Brisbane Z, noticeable on Lunar Orbiter 4's photograph LOIV-178-h3, North is toward the bottom of the frame).
  • Watt (Van Langren's Zamosci, together with Steinheil).

Farside Named Features

(The following features are not formally included in the present Rükl rectangle, but they are adjacent to it and their centers are less than 10° beyond the mean limb -- so they may be seen here in whole or in part with a favorable libration)

Additional Information


Why is Brisbane Z called ORIS by some?

  • ORIS. This name is (or was?) used repeatedly by Gillis and Spudis for a crater at 53°S/72°E in their 1998 paper describing far-side mare basalts. Appears to be a reference to Brisbane Z. Origin of, and reason for, non-standard name unknown. Noticed by Stephen J. Saber.
  • Why the name ORIS on the moon? I think I have the answer, or perhaps it's just a far-fetched hypothesis... The origin of the name ORIS (Brisbane Z) is a difficult one, because all you get from the internet is an awful lot of photographs of luxury wristwatches from the Swiss company ORIS, and a Wikipedia-page about that company, but wait a minute... there seems to have been something in 1968 related to astronomy, because in that year ORIS obtained full chronometer certification from the Neuchatel Observatory for movement cal.652 (don't ask me about the meaning of movement cal.652, I don't know). NOW... could it be that the moon's southeastern limb crater Brisbane Z (our ORIS) was used as a signpost or landmark for occultations of stars or planets, and that the exact time of reappearance of the occulted star (or planet) was measured with a chronometer (or watch) from the ORIS company? I know, it looks far-fetched, but maybe this could be the reason why limb crater Brisbane Z was called ORIS... See: Neuchatel Observatory, and: ORIS (Swiss company of luxury wristwatches). - DannyCaes DannyCaes Oct 10, 2015
