Nearside Named Features

• Aston
• Bunsen
• Dechen
• Dorsa Dechen - Harding (an unofficial name from D.Caes for the system of wrinkle ridges between and near Dechen and Harding).
• Dorsa Lavoisier A (an unofficial name from D.Caes for the system of wrinkle ridges east-northeast of Lavoisier A).
• Dorsa Nielsen-Rumker (an unofficial name from D.Caes for the system of wrinkle ridges running from Nielsen to Mons Rumker, see Additional Information below).
• Dorsum Dechen A (an unofficial name from D.Caes for the wrinkle ridge running across the bowl-shaped crater Dechen A, east of Dechen itself).
• Dorsum Harding D (an unofficial name from D.Caes for the wrinkle ridge which runs across Harding D east of Harding itself).
• Dorsum Lavoisier C (an unofficial name from D.Caes for the wrinkle ridge which starts at Lavoisier C, running southeastward to stop at the hills west of Lichtenberg).
• Dorsum Naumann B (an unofficial name from D.Caes for the wrinkle ridge north of Naumann B, west of Mons Rumker).
• Dorsum Scilla
• Dorsum Wollaston V (the wrinkle ridge north of Wollaston V, a bowl-shaped craterlet north of Montes Agricola).
• Fossa Caruso (a disallowed name for the elongated depression southeast of Nielsen, see Lunar Topographic Orthophotomap 38-B2).
• Gerard
• Harding
• Humason
• Lavoisier
• Lichtenberg (J.Hewelcke's Mons Alabastrinus) (note: Lichtenberg is one of the most famous hot spots of reddish colored Transient Lunar Phenomena, see Additional Information below).
• Lichtenberg hills (an unofficial name from D.Caes for the hills northeast and west of Lichtenberg). These hills are Lichtenberg Epsilon (hill west of Lichtenberg), and Lichtenberg Beta (hill northeast of Lichtenberg), see chart SLC F2 (System of Lunar Craters, 1966), and also page 247 in Tony Dethier's Maanmonografieen (VVS - Vereniging Voor Sterrenkunde, 1989).
• Lichtenberg's ghost (a nickname from D.Caes for the ghost crater immediately north-northwest of Lichtenberg).
• Littus Eclipticum (Riccioli's discontinued name for the limb region of Chart 8) (the exact pinpoint locations of the northern and southern boundaries of this region are unknown) (Van Langren called it Littus Philippicum).
• Mons Rümker
• Montes Agricola (the most northern part of it, which is captured near the lower right corner of Chart 8) (see Chart 18 for its southwestern part).
• Najera (a disallowed name from H.P.Wilkins for a near-the-limb crater, located at the upper right corner of Chart 8) (south of Galvani, see Chart 1).
• Naumann
• Nielsen
• Nielsen's keyhole (a nickname from D.Caes for the keyhole-shaped double craterlet northwest of Nielsen) (this curious "8"-shaped or Peanut-shaped craterlet (a system of two connected craterlets with high rim) is described and depicted in NASA SP-362 Apollo Over the Moon, Chapter 4: The Maria (Part 3), Figure 89. Note: the photo-number which is mentioned below the depicted photograph (in AOTM) should be 10344, and not "0344"!) (Nielsen's keyhole is also noticeable near the upper right corner of Lunar Orbiter 4's Frame 163-H1).
• Oceanus Procellarum (the northwestern part of it, occupying the lower half of Chart 8).
• Paludes Orient (J.Hewelcke's disallowed name for the northwestern "edge" of Oceanus Procellarum).
• Rima Cleopatra
• Rimae Gerard
• Sinus Roris (J.Hewelcke's Sinus Hyperboreus) (the western part of it, occupying the upper corner of Chart 8).
• Stamp mountain (a nickname from D.Caes for the system of two "stamp-shaped " hills immediately north of an unnamed bowl-shaped crater, due south-southeast of Mons Rumker). See http://bit.ly/2uILkwi
• Telemann Unit (an unofficial name for a slightly colored area near Naumann and Lavoisier A).
• Ulugh Beigh
• von Braun
• Wollaston Epsilon (the small hillock west of Nielsen, the bowl-shaped crater which was once called Wollaston C).

Transient Lunar Phenomena near Lichtenberg

• During the history of lunar observing, many reddish (or pink-colored) glows have been observed near crater Lichtenberg. One observation of such a red coloration (related to Lichtenberg and its environs) is described in Harold Hill's book A Portfolio of Lunar Drawings. This description is also online in the page Colored Regions on the Moon's Surface (Part 1). - DannyCaes Nov 10, 2008

Dorsa Nielsen-Rumker

• The eastern part of this map is occupied by an officially unnamed (yet pronounced) system of wrinkle ridges, running from Nielsen (near the map's lower right corner) to Mons Rumker (a little above center of the right margin). An impressive orbital photograph of this wrinkle ridge was made during the mission of Apollo 15 in the summer of 1971. See: AS15-88-11983. - DannyCaes Nov 20, 2008
• One could only guess why there is no officially recognized name for that system of wrinkle ridges (it is an eye-catching telescopic object, especially during local sunrise or sunset circumstances!). - DannyCaes Oct 2, 2015
