Named Features

• Arcology Row (a somewhat strange unofficial name for the eastern "leg" of the Lunar V which is always visible during First Quarter Moon).
• Blagg
• Bode (Van Langren's Pratii) (?) (E.A.Whitaker seems to be uncertain about that one).
• Bode Pyroclastics (an unofficial name, incorporated on charts 17 and 18 of the 21st Century Atlas of the Moon by C.A. Wood, M. Collins) (this is the rough region between Sinus Aestuum and Mare Vaporum).
• Bright dot (a nickname from D.Caes for the exceptionally bright starlike ejectablanket around a tiny young craterlet at the western rim of Mare Vaporum, located near the upper margin of Chart 33, or the lower margin of Chart 22) (see also LAC 59, page 118, in the Clementine Atlas of the Moon, B.Bussey/ P.Spudis).
• Bruce (not to be confused with NASA's Cape Bruce northwest of Censorinus!).
• Chladni
• Dorsum Blagg (an unofficial name from D.Caes for the wrinkle ridge which is running across Sinus Medii, through Blagg).
• Dorsa Hyginus D (an unofficial name from D.Caes for the system of wrinkle ridges northwest of the bowl-shaped crater Hyginus D and slightly east of the western "coast" of Mare Vaporum).
• Face of the Woman in the Full Moon (the combination of Mare Vaporum and Sinus Medii, and also Sinus Aestuum on Rukl's 32).
• Gun carriage (a nickname from D.Caes for an irregular cluster of craterlets which looks very much like a gun carriage, located east-northeast of Schroter).
• Hellespontum, Sinus Propont. ad (J.Hewelcke's disallowed name for the western corner of Mare Vaporum).
• Lunar V (an unofficial name from D.Caes for a distinct clair-obscur phenomenon just east-northeast of Ukert, always visible during First Quarter Moon, simultaneously with the well-known Lunar X at Purbach).
• Mare Vaporum (Van Langren's Fretum Catholicum).
• Murchison (Van Langren's Arenbergii, J.Hewelcke's Mons Pangaeus).
• Pallas (Van Langren's Arenbergii, J.Hewelcke's Mons Pangaeus).
• Rhaeticus (J.Hewelcke's Mons Mysius).
• Rimae Bode
• Rimae Triesnecker
• Schroter swirls (an unofficial name from D.Caes for a possible field of very weak Reiner Gamma type swirls east of Schroter) (this is the mare-like region between Schroter and Sinus Medii) (to see this field of possible swirls, one should take a look at the shadowless WAC albedo-mosaic of the LROC's Act-React Quick Map, and the page Possible swirl field east of Schroter).
• Sinus Aestuum (Van Langren's Fretum Catholicum, J.Hewelcke's Mare Adriaticum) (only the eastern part of Sinus Aestuum is seen here, occupying the upper left section of Chart 33).
• Sinus Medii (Van Langren's Sinus Medius, J.Hewelcke's Mare Adriaticum) (see also the Lunar Heliotrope project, aka Project Pharos) (a large sunlight reflecting mirror on top of an unmanned rover to create a lighthouse effect and to observe the minute speck of light through very powerful telescopes).
• Sinus Propontis (J.Hewelcke's disallowed name for the southern part of Mare Vaporum).
• Stuart's craterlet (an unofficial name from D.Caes for the fresh craterlet near Pallas which was created by the impact of a small asteroid in 1953, observed by Dr. L.H.Stuart, see Additional Information below).
• Surveyor 4 (crash-landed on July 17, 1967, west-southwest of Bruce) (0.45° North/ 1.39° West, according to Wikipedia).
• Surveyor 6 (soft-landed on November 10, 1967, west-southwest of Bruce, very near the impact craterlet of Surveyor 4) (Surveyor 6 on the plains of Sinus Medii).
• Terra Nivium (Riccioli's discontinued name for the western part of Chart 33).
• Triesnecker (Van Langren's Bechleri).
• Ukert (Van Langren's Stratii, J.Hewelcke's Mons Pangaeus).
• Vallis Ukert (an unofficial name from D.Caes for the the valley southwest of Ukert, which is part of the Imbrium radial sculpture).

Stuart's craterlet

On November 15, 1953, the physician and amateur astronomer Dr. Leon H. Stuart took a picture of the Moon that appeared to show a flare of light about 16 km southeast of Pallas. The flare was estimated to last for about 8–10 seconds. The report was published in a 1956 issue of The Strolling Astronomer, a newsletter. However the incident was dismissed by professionals of the period as more likely a meteoroid entering the Earth's atmosphere.
  Many years later Dr. Bonnie Buratti of JPL saw the photograph and decided to investigate. Assisted by a graduate student, she identified a 1.5 km. diameter crater imaged by the Clementine spacecraft. The crater has the correct size, shape, and albedo to match the expected impact energy. Some astronomers now agree that Dr. Stuart may indeed have photographed an asteroid impact on the Moon.
