Nearside Named Features

  • Aegyptus (regio) (J.Hewelcke's disallowed name for the southwestern highlands).
  • Baade (once called Asaph Hall by J.H.Franz).
  • Basaltic Lava Areas (an unofficial name from H.Hill for the low-albedo lakes south of Vieta, north of Lacroix) (also called Honey Lake). The region south of Vieta (between Lehmann and Vieta) seems to be occupied by several rather large unnamed craters (or vaguely observable small impact basins). That's how it looks on SLC map F7.
  • Catalán
  • Comas Sola (a disallowed name from H.P.Wilkins, probably for H.Hill's Basaltic Lava Areas south of Vieta).
  • Fourier (J.Hewelcke's Mons Casius) (note: together with the IAU's Vieta this is the first one of J.Hewelcke's Montes Casius, the second one is the IAU's Agatharchides P).
  • Graff
  • Illuminated cross near Fourier (a clair-obscur phenomenon discovered by D.Caes, located at approximately 33 degrees South/ 53 degrees West, morning-terminator at 46-47 degrees West).
  • Lacroix
  • Lacus Fourier (an unofficial name from D.Caes for the low-albedo spot between Fourier and Fourier A) (immediately west of Fourier A).
  • Lagrange
  • Mons Eos (J.Hewelcke's disallowed name for the bright and dark areas east of Piazzi).
  • Morgues (Van Langren's disallowed name for a low-albedo spot near Fourier) (could this have been H.Hill's Basaltic Lava Areas?).
  • Piazzi
  • Scithiae pars (J.Hewelcke's disallowed name for the southwestern limb area).
  • Shaler
  • Terra Caloris (Riccioli's discontinued name for the whole of Chart 61).
  • Terra Sterilitatis (Riccioli's discontinued name for the southwestern limb region) (which means: Riccioli must have been aware of the phenomenon known as libration) (see also: Farside Features, below).
  • Unexpected remains of a possible basin (see this page).
  • Vallis Baade
  • Vallis Bouvard
  • Vallis Inghirami
  • Wright

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)
  • Drude
  • Focas
  • Guthnick
  • Heyrovsky
  • Mare Pacificus (an unofficial name, also known as: Orientale Dark Mantle Ring Deposit) (see also Rukl's 50 for the northern part of it).
  • Mendel-Rydberg Basin (an unofficial name).
  • Rydberg
  • Terra Sterilitatis (Riccioli's discontinued name for the southwestern limb region, only visible during favorable libration).
