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.

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."

Béla Crater Resides in Southeastern Mare Imbrium on Lunar Near Side

Summary: Béla Crater resides in the southeastern Mare Imbrium on the lunar near side in a quartet of craters that neighbors in southern Rima Hadley.

Detail of Near Side Shaded Relief and Color-Coded Topography Map shows Béla's (left center) Rima Hadley neighborhood in southeastern Mare Imbrium: USGS Astrogeology Science Center / Gazetteer of Planetary Nomenclature

Béla Crater resides in the southeastern Mare Imbrium on the lunar near side in a quartet of northeastern quadrant craters that neighbor in southern Rima Hadley.

Béla Crater is centered at 24.67 degrees north latitude, 2.27 degrees east longitude, according to the International Astronomical Union's (IAU) Gazetteer of Planetary Nomenclature. The northeastern quadrant crater establishes its northernmost and southernmost latitudes at 24.84 degrees north and 24.51 degrees north, respectively. It finds its easternmost and westernmost longitudes at 2.34 degrees east and 2.23 degrees east. Béla Crater has a diameter of 10.07 kilometers.

Béla Crater is located in the southeastern edge of Mare Imbrium. Béla Crater is positioned to the southwest of the highland break that marks the joining of eastern Mare Imbrium with western Mare Serenitatis.

Mare Imbrium ("Sea of Showers") stretches across the northern near side as the second largest of the moon's dark, basaltic plains (Latin: maria, "sea"; maria, "seas"). Mare Imbrium's territorial expanse includes crossing the lunar prime meridian, measured at 0 degrees of longitude, to qualify it for northwestern and northeastern quadrant occupancy.

Mare Imbrium is centered at 34.72 degrees north latitude, minus 14.91 degrees west longitude. Its northernmost and southernmost latitudes stretch to 51.46 degrees north and 15.23 degrees north, respectively. Its easternmost and westernmost longitudes extend to 8.56 degrees east and minus 38.36 degrees west, respectively. Mare Imbrium's diameter spans 1,145.53 kilometers.

Béla Crater is sited at the southern end of Rima Hadley. The fissure (Latin: rima, "fissure") zigzags to the northwest of southeastern Mare Imbrium's Montes Appeninus.

Known informally as Hadley Rille, Rima Hadley is centered at 25.72 degrees north latitude, 3.15 degrees east longitude. The rille obtains its northernmost and southernmost latitudes at 26.7 degrees north and 24.53 degrees north, respectively. It marks its easternmost and westernmost longitudes at 3.58 degrees east and 2.26 degrees east, respectively. Rima Hadley diameter measures 116.09 kilometers.

Carlos, Jomo and Taizo form a quartet with Béla as nearest named craters neighboring in southern Rima Hadley. Carlos lies to the north, on the same side of the rille as Béla. Jomo is located to the southeast of Béla. Taizo's siting on the western side of the rille's south end, opposite and slightly west-northwest of Béla, qualifies it as the closer of Béla two neighbors.

Carlos is centered at 24.91 degrees north latitude, 2.28 degrees west longitude. The small crater posts northernmost and southernmost latitudes of 24.99 degrees north and 24.84 degrees north, respectively. It places its easternmost and westernmost longitudes at 2.31 degrees west and 2.25 degrees west, respectively. Carlos has a diameter of 4.67 kilometers.

Jomo is centered at 24.41 degrees north latitude, 2.44 degrees west longitude. It finds its northernmost and southernmost latitudes at 24.51 degrees north and 24.31 degrees north, respectively. It establishes its easternmost and westernmost longitudes at 2.56 degrees east and 2.33 degrees east, respectively. Jomo's diameter measures 7.36 kilometers.

Taizo is centered at 24.7 degrees north latitude, 2.2 degrees east longitude. Its northernmost and southernmost latitudes occur at 24.84 degrees north and 24.57 degrees north, respectively. It obtains its easternmost and westernmost longitudes at 2.23 degrees east and 2.16 degrees east, respectively. Taizo's diameter measures 8.19 kilometers.

Béla's residence in southern Rima Hadley places the northern hemisphere crater to the northwest of Montes Appeninus. The rugged range marks Mare Imbrium's southeastern edges.

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

Béla 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). Béla is plotted on NASA Lunar Topophotomap 41B4S3, which was published in May 1975. The map's Names Information lists "Béla, Carlos, Jomo, Taizo" as unofficial names used "only for the identification of features on this map."

The International Astronomical Union approved Béla as the crater's official name in 1976. The Gazetteer of Planetary Nomenclature identifies Béla as a "Hungarian male name, also Slovak female name."

Ann Craterlet Resides in Southeastern Mare Imbrium on Lunar Near Side

Summary: Ann Craterlet resides in southeastern Mare Imbrium on the lunar near side as a string of northern hemisphere craterlets northwest of Montes Appeninus.

Detail of Near Side Shaded Relief and Color-Coded Topography Map shows Ann's (left center; between Rimae Archimedes and Rima Bradley) Montes Apenninus neighborhood in southeastern Mare Imbrium: USGS Astrogeology Science Center / Gazetteer of Planetary Nomenclature

Ann Craterlet resides in southeastern Mare Imbrium on the lunar near side in a string of four northern hemisphere craterlets that neighbor to the northwest of Montes Appeninus.

Ann is centered at 25.11 degrees north latitude, minus 0.05 degrees west longitude, according to the International Astronomical Union's (IAU) Gazetteer of Planetary Nomenclature. The northern hemisphere craterlet finds its northernmost and southernmost latitudes at 25.13 degrees north and 25.09 degrees north, respectively. It establishes its easternmost and westernmost longitudes at minus 0.02 degrees west and minus 0.09 degrees west, respectively. Ann has a diameter of 2.12 kilometers.

Ann Craterlet is located in the southeastern edge of Mare Imbrium. Ann lies to the southwest of the highland break that marks the joining of eastern Mare Imbrium with western Mare Serenitatis.

The large, dark, basaltic plain known as Mare Imbrium ("Sea of Showers") primarily occupies the lunar near side's northwestern quadrant. Easternmost Mare Imbrium extends across the moon's prime meridian, which marks 0 degrees of longitude, to invade the northeastern quadrant.

Mare Imbrium is centered at 34.72 degrees north latitude, minus 14.91 degrees west longitude. Its northernmost and southernmost latitudes extend to 51.46 degrees north and 15.23 degrees north, respectively. Its easternmost and westernmost longitudes stretch to 8.56 degrees east and minus 38.36 degrees west, respectively. Mare Imbrium's diameter spans 1,145.53 kilometers.

Michael occurs as the named crater neighboring nearest to Ann Craterlet in Mare Imbrium. Lying to the southeast of Ann, Michael resides, east of the moon's prime meridian, in the near side's northeastern quadrant.

Michael is centered at 25.05 degrees north latitude, 0.21 degrees east longitude. The northeastern quadrant craterlet posts northernmost and southernmost latitudes of 25.08 degrees north and 25.02 degrees north, respectively. It marks its easternmost and westernmost longitudes at 0.28 degrees east and 0.15 degrees east, respectively. Michael's diameter measures 3.46 kilometers.

As Michael's southeastern neighbor, Patricia lies to the southeast of Ann. As with Michael, Patricia is located in the near side's northeastern quadrant.

Patricia is centered at 24.91 degrees north latitude, 0.5 degrees east longitude. The northeastern quadrant craterlet obtains its northernmost and southernmost latitudes at 24.99 degrees north and 24.81 degrees north, respectively. It places its easternmost and westernmost longitudes at 0.66 degrees east and 0.33 degrees east, respectively. Patricia's diameter measures 10.08 kilometers.

Kathleen lies to the northwest of Ann, Michael and Patricia. Kathleen joins Ann as a northwestern quadrant occupant, versus the northeastern quadrant occurrences of Michael and Patricia.

Kathleen is centered at 25.34 degrees north latitude, minus 0.83 degrees west longitude. The northwestern quadrant craterlet records northernmost and southernmost latitudes of 25.39 degrees north and 25.3 degrees north, respectively. It registers easternmost and westernmost longitudes of minus 0.74 degrees west and minus 0.93 degrees west, respectively. Kathleen's diameter measures 5.37 kilometers.

The string of four named craterlets to which Ann belongs finds Kathleen as the northernmost and westernmost of the four. Patricia qualifies as the easternmost and southernmost of the four.

Patricia's diameter of 10.08 kilometers qualifies as the largest of the four. Ann's diameter of 2.12 kilometers places as the smallest of the four. Kathleen's 5.37 kilometers and Michael's 3.46 kilometers rate as the second and third largest diameters, respectively, of the four.

The near side's two northern quadrants are represented equally by the string of four craterlets. Ann and Kathleen are located in the northwestern quadrant. Michael and Patricia are sited in the northeastern quadrant.

Ann's string veers to the northwest of the mountainous terrain that edges southeastern Mare Imbrium. Montes Appeninus trends northeast-southwest as the range defines Mare Imbrium's southeastern border. As with Mare Imbrium, the mountain range straddles the moon's prime meridian, with territory in both northern quadrants.

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

Ann 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). Ann is plotted on NASA Lunar Topophotomap 41A3S1, which was published in August 1974. The map's Names Information lists "Ann, Ian, Kathleen, Michael, Patricia, Vladimir" as unofficial names used "only for the identification of features on this map."

The International Astronomical Union approved Ann as the craterlet's official name in 1976. The Gazetteer of Planetary Nomenclature notes Ann as: "Hebrew female name."
