Donna resides in southeastern Mare Tranquillitatis on the lunar near side in the northeast quadrant to the west of northwestern Mare Fecunditatis.

Donna Craterlet is centered at 7.22 degrees north latitude, 38.3 degrees east longitude, according to the International Astronomical Union's (IAU) Gazetteer of Planetary Nomenclature. The northeastern quadrant craterlet marks its northernmost and southernmost latitudes at 7.24 degrees north and 7.2 degrees north, respectively. It posts easternmost and westernmost longitudes of 38.33 degrees east and 38.27 degrees east, respectively. Donna has a diameter of 1.84 kilometers.

Donna Craterlet is sited in southeastern Mare Tranquillitatis. The Gazetteer of Planetary Nomenclature's Descriptor Terms (Feature Types) webpage defines a lunar mare (Latin: "sea"; maria, "seas") as "'Sea'; on the Moon, low albedo, relatively smooth plain, generally of large extent." Mare Tranquillitatis primarily occupies the near side's northeastern quadrant but also includes terrain in the southeastern quadrant.

Mare Tranquillitatis ("Sea of Tranquility") is centered at 8.35 degrees north latitude, 30.83 degrees east longitude. The dark, basaltic plain's northernmost and southernmost latitudes tap 19.37 degrees north and minus 4.05 degrees south, respectively. The lunar mare's easternmost and westernmost longitudes touch 45.49 degrees east and 16.92 degrees east, respectively. Mare Tranquillitatis has a diameter of 875.75 kilometers.

Donna's location near the southeastern fringes of Mare Tranquillitatis places the craterlet to the west of the Sea of Tranquility's meeting with northwestern Mare Fecunditatis. The Sea of Tranquility's southeastern neighbor primarily occupies the near side's southeastern quadrant but also extends into the northeastern quadrant.

Mare Fecunditatis ("Sea of Fecundity") is centered at minus 7.83 degrees south latitude, 53.67 degrees east longitude. The lunar mare's northernmost and southernmost latitudes reach 6.11 degrees north and minus 21.7 degrees south, respectively. The eastern hemisphere plain's easternmost and westernmost longitudes extend to 63.34 degrees east and 40.77 degrees east, respectively. Mare Fecunditatis has a diameter of 840.35 kilometers.

Donna neighbors with closest named eastern craters Cauchy C and Zähringer in southeastern Mare Tranquillitatis. Cauchy C lies to the northeast of Donna. Zähringer is positioned to the southeast of Donna.

Cauchy C belongs to the 10-satellite Cauchy Crater system. Cauchy C is centered at 8.16 degrees north latitude, 38.86 degrees east longitude. Satellite C establishes its northernmost and southernmost latitudes at 8.22 degrees north and 8.1 degrees north, respectively. It places its easternmost and westernmost longitudes at 38.92 degrees east and 38.8 degrees east, respectively. Cauchy C has a diameter of 3.6 kilometers.

Zähringer Crater is centered at 5.51 degrees north latitude, 40.21 degrees east longitude. The bowl-shaped crater reports northernmost and southernmost latitudes of 5.69 degrees north and 5.33 degrees north, respectively. It gives its easternmost and westernmost longitudes as 40.4 degrees east and 40.03 degrees east, respectively. Zähringer's diameter measures 11.19 kilometers.

Cauchy M and Aryabhata are situated as Donna Craterlet's closest named western craters. Cauchy M lies to the northwest of Donna. Aryabhata Crater is located to the southwest of Donna.

Cauchy M occurs as the most southerly and westerly of the Cauchy Crater system's 10 satellites. Cauchy M lies to the southwest of Cauchy C, Donna's northeastern neighbor.

Cauchy M is centered at 7.62 degrees north latitude, 35.05 degrees east longitude. Satellite M maintains northernmost and southernmost latitudes of 7.67 degrees north and 7.56 degrees north, respectively. It obtains easternmost and westernmost longitudes of 35.1 degrees east and 34.99 degrees east, respectively. Cauchy M has a diameter of 3.36 kilometers.

Aryabhata, Donna Craterlet's southwestern neighbor, is centered at 6.2 degrees north latitude, 35.17 degrees east longitude. The mostly lava-submerged crater records northernmost and southernmost latitudes of 6.56 degrees north and 5.84 degrees north, respectively. The arc-shaped, lunar impact crater remnant registers easternmost and westernmost longitudes of 35.54 degrees east and 34.81 degrees east, respectively. Aryabhata's diameter measures 21.89 kilometers.

Donna numbers among 95 minor features identified with first-name designations on lunar topophotomaps prepared and published by The Defense Mapping Agency (DMA) for the National Aeronautics and Space Administration (NASA). Donna is plotted on NASA Lunar Topophotomap 61D2S1, which was published in May 1977. The map's Names Information lists Donna as "a provisional name pending IAU approval."

The International Astronomical Union approved Donna as the craterlet's name in 1979. The Gazetteer of Planetary Nomenclature finds Donna's origin as: "Italian female name."

Julienne Resides in Mare Imbrium's Palus Putredinis on Lunar Near Side

Summary: Julienne resides in Mare Imbrium's Palus Putredinis on the lunar near side as a northeast quadrant craterlet southwest of the Apollo 15 Landing Site.

Detail of Near Side Shaded Relief and Color-Coded Topography Map shows Julienne's (center; above Rima Hadley) Palus Putredinis neighborhood in lunar near side's southeastern Mare Imbrium: USGS Astrogeology Science Center / Gazetteer of Planetary Nomenclature

Julienne is centered at 26.06 degrees north latitude, 3.13 degrees east longitude, according to the International Astronomical Union's (IAU) Gazetteer of Planetary Nomenclature. The depression's northernmost and southernmost latitudes are listed as 26.09 degrees north and 26.03 degrees north, respectively. Its easternmost and westernmost longitudes are given as 3.14 degrees east and 3.11 degrees east, respectively. Julienne has a diameter of 1.8 kilometers.

Dumbbell- or peanut-shaped Julienne is situated in the southeastern reaches of Palus Putredinis. Palus (Latin: "marsh, swamp") is a geological feature defined by the Gazetteer of Planetary Nomenclature's Descriptor Terms (Feature Types) webpage as: "'Swamp'; small plain."

Palus Putredinis ("Marsh of Decay") is centered at 27.36 degrees north latitude, 0 degrees of longitude. The small, lava-flooded plain achieves its northernmost and southernmost latitudes at 29.4 degrees north and 25.31 degrees north, respectively. The northern hemisphere plain maintains its easternmost and westernmost longitudes at 2.85 degrees north and minus 2.77 degrees south, respectively. Palus Putredinis has a diameter of 180.45 kilometers.

Palus Putredinis is located in southeastern Mare Imbrium. The lunar mare (Latin: "sea"; maria, "seas") extends its territory across the lunar prime meridian of 0 degrees of longitude to establish occupancy in both the northwestern and northeastern quadrants.

Mare Imbrium ("Sea of Showers") is centered at 34.72 degrees north latitude, minus 14.91 degrees west longitude. Its northernmost and southernmost latitudes span 51.46 degrees north to 15.23 degrees north, respectively. Its easternmost and westernmost longitudes tap 8.56 degrees east and minus 38.36 degrees west, respectively. Mare Imbrium's diameter spans 1,145.53 kilometers.

Julienne is located to the west of Rima Hadley. The fissure (Latin: rima, "fissure") trends south-north in its sinuous parallel of its eastern neighbor, Montes Apenninus.

Rima Hadley is centered at 25.72 degrees north latitude, 3.15 degrees east longitude. The rille (German: "channel") records northernmost and southernmost latitudes of 26.7 degrees north and 24.53 degrees north, respectively. Hadley Rille registers easternmost and westernmost longitudes of 3.58 degrees east and 2.26 degrees east, respectively. Rima Hadley's diameter measures 116.09 kilometers.

Hadley C lies south-southwest of Julienne. Part of the crater's eastern side makes contact with Rima Hadley.

Hadley C is centered at 25.48 degrees north, 2.8 degrees east longitude. The crater marks its northernmost and southernmost latitudes at 25.58 degrees north and 25.39 degrees north, respectively. It posts easternmost and westernmost longitudes of 2.91 degrees east and 2.7 degrees east, respectively. Hadley C's diameter measures 5.8 kilometers.

St. George is situated to the southeast of Julienne. The craterlet overlooks the eastern side of Rima Hadley from its location on the northwestern flank of Mons Hadley Delta, a massif in northern Montes Apenninus.

St. George is centered at 25.96 degrees north latitude, 3.54 degrees east longitude. The depression obtains its northernmost and southernmost latitudes at 26 degrees north and 25.92 degrees north, respectively. It places its easternmost and westernmost longitudes at 3.58 degrees east and 3.5 degrees east, respectively. St. George has a diameter of 2.42 kilometers.

The Apollo 15 Landing Site, Hadley Base, is found to the northeast of Julienne, on the opposite side of Rima Hadley. Lunar Module (LM) Falcon landed Friday, July 30, 1971, on the lava plain east of Rima Hadley, north of Mons Hadley Delta and southwest of Mons Hadley.

Mons Hadley Delta is centered at 25.72 degrees north latitude, 3.71 degrees east longitude. The massif establishes its northernmost and southernmost latitudes at 25.99 degrees north and 25.44 degrees north, respectively. It finds its easternmost and westernmost longitudes at 3.86 degrees east and 3.46 degrees east, respectively. Mons Hadley Delta's diameter measures 17.24 kilometers.

Mons Hadley juts westward toward southeastern Mare Imbrium. British selenographer Thomas Gwyn Empy Elger (Oct. 27, 1836-Jan. 9, 1897) described Mount Hadley as: "The northern extremity of the Apennines" (page 156) in his Victorian era lunar guide (1895), The Moon: A Full Description and Map of Its Principal Physical Features.

Mons Hadley is centered at 26.69 degrees north latitude, 4.12 degrees east longitude. The massif reports northernmost and southernmost latitudes of 27.13 degrees north and 26.32 degrees north, respectively. Its easternmost and westernmost longitudes are detailed as 4.4 degrees east and 3.74 degrees east, respectively. Mons Hadley's diameter measures 26.4 kilometers.

Julienne numbers among 95 minor features identified with first-name designations on lunar topophotomaps prepared and published by The Defense Mapping Agency (DMA) for the National Aeronautics and Space Administration (NASA). Julienne is plotted on NASA Lunar Topophotomap 41B4S1, which was published in November 1974. The map's Names Information lists "Julienne" as unofficial name used "only for the identification of features on this map."

The International Astronomical Union approved Julienne as the craterlet's official name in 1976. The Gazetteer of Planetary Nomenclature originates Julienne as: "French female name."

Dag Craterlet Resides in Lacus Felicitatis on Lunar Near Side

Summary: Dag Craterlet resides in Lacus Felicitatis on the lunar near side in the northeastern quadrant with Ina and Osama as nearest named craters.

Detail of Near Side Shaded Relief and Color-Coded Topography Map shows Dag's (lower center right) Lacus Felicitatis neighborhood south of Montes Apenninus: USGS Astrogeology Science Center / Gazetteer of Planetary Nomenclature

Dag Craterlet resides in Lacus Felicitatis on the lunar near side as a northeastern quadrant trio with nearest named craters Ina and Osama.

Dag is centered at 18.71 degrees north latitude, 5.26 degrees east longitude, according to the International Astronomical Union's (IAU) Gazetteer of Planetary Nomenclature. The northern hemisphere craterlet maintains its northernmost and southernmost latitudes at 18.72 degrees north and 18.7 degrees north, respectively. The northeastern quadrant craterlet marks its easternmost and westernmost longitudes at 5.27 degrees east and 5.26 degrees east, respectively. Dag has a diameter of 0.36 kilometers.

Dag Craterlet is located in Lacus Felicitatis. The Gazetteer of Planetary Nomenclature's Descriptor Terms (Feature Types) webpage defines "Lacus, lacūs" as: "'Lake' or small plain." Lacus Felicitatis ("Lake of Happiness") presents a bent outline, with a large, northwest-southeast-aligned west wing and an eastern wing.

Lacus Felicitatis is centered at 18.52 degrees north latitude, 5.36 degrees east longitude. The northeastern quadrant small plain establishes its northernmost and southernmost latitudes at 19.56 degrees north and 17.66 degrees north, respectively. It posts easternmost and westernmost longitudes of 7.05 degrees east and 3.67 degrees east, respectively. Lacus Felicitatis has a diameter of 98.48 kilometers.

Dag occupies the small plain's eastern wing with Ina and Osama as nearest named craters. Ina and Osama lie to the south, with Ina intervening between Dag and Osama.

Ina outlines as a sideways capital letter D. Osama is positioned in southwestern proximity to Ina.

Ina is centered at 18.66 degrees north latitude, 5.3 degrees east longitude. The small crater's northernmost and southernmost latitudes are given as 18.69 degrees north and 18.62 degrees north, respectively. Its easternmost and westernmost longitudes are identified as 5.35 east and 5.26 degrees east, respectively. Ina's diameter measures 2.98 kilometers.

Mons Agnes is sited on the interior floor in eastern Ina. Its location places it to the southeast of Dag and to the northeast of Osama.

Mons Agnes is centered at 18.66 degrees north latitude, 5.33 degrees east longitude. The hilly feature's northernmost and southernmost latitudes repeat its center latitude, 18.66 degrees north. Its easternmost and westernmost longitudes are reported identically as 5.34 degrees east. Zero kilometers is given as the unknown diameter for Mons Agnes.

Osama is centered at 18.61 degrees north latitude, 5.27 degrees east longitude. It places its northernmost and southernmost latitudes at 18.62 degrees north and 18.6 degrees north, respectively. It finds its easternmost and westernmost longitudes at 5.27 degrees east and 5.26 degrees east, respectively. Osama has a diameter of 0.42 kilometers.

Dag's occurrence in Lacus Felicitatis places it in the northeastern quadrant region that forms the southern end of the break between southeastern Mare Imbrium and southwestern Mare Serenitatis. The ranges of Montes Appeninus and Montes Haemus border southeastern Mare Imbrium and southwestern Mare Serenitatis, respectively. Montes Appeninus and Montes Haemus form northwestern and northeastern borders, respectively, for the highland terrain that surrounds Lacus Felicitatis.

The Montes Haemus range is centered at 17.11 degrees north latitude, 12.03 degrees east longitude. The range's northernmost and southernmost latitudes touch 23.16 degrees north and 14.08 degrees north, respectively. The range's easternmost and westernmost longitudes tap 21.14 degrees east and 4.66 degrees east, respectively. The Montes Haemus range's diameter measures 384.66 kilometers.

The Montes Appeninus ("Appenine Mountains") range is centered at 19.87 degrees north latitude, 0.03 degrees east longitude. The range's northernmost and southernmost latitudes span 28.47 degrees north to 14.63 degrees north, respectively. The range's easternmost and westernmost longitudes extend 7.34 degrees east and minus 10.21 degrees west, respectively. The diameter, or greatest length, of Montes Appeninus spans 599.67 kilometers.

Dag numbers among 95 minor features identified with first-name designations on lunar topophotomaps prepared and published by The Defense Mapping Agency (DMA) for the National Aeronautics and Space Administration (NASA). Dag is plotted on NASA Lunar Topophotomap 41C3S1, which was published in July 1974. The map's Names Information lists "Agnes, Dag, Ina, Osama" as unofficial names used "only for the identification of features on this map."

The International Astronomical Union approved Dag as the craterlet's official name in 1976. The Gazetteer of Planetary Nomenclature recognizes Dag as: "Scandinavian male name."
