Rima Hygimis 2()iM.09.0E 21:23 UT Age 21 days. 10-ln f/6 Newtonian + 2.SX + 1.6X + ToUcam, 47 frames. The crater in the middle of the rille is Hyginus. It is rimless, has flat floor and hence appears volcanic rather than impact-created. Presumably Hygintis Is volcanic, it would be a lava outlet and the riile would be a lava channel.

Montes Apenninus
Sinus Aestuum & Eratosthenes 20D5.05.17 -12:30 UT Age 9 days. 10-in fifi Newtonian + 2.5X + ToUcam

Montes Apenninus 3.70 W 18. 90 N

The largest mountain range on the nearside of the Moon, named by the Polish astronomer and selenographer Hevelius (1611-1687). It is on the south-eastern edge of Mare Imbrium (Sea of Rains), and is part of the rising rim of the impact basin that holds the mare. Apenninus measures about 500 km end-to-end, 5000 m peak. The mountain slopes towards Mare Imbrium are rather steep (roughly 30o) but the back slopes towards south are gradual. The back slopes are believed massive deposits of the ejecta produced by the Imbrium impact. See also T257 in [Map 33

Montes Apenninus is very bright at days close to the full moon.

Sinus Aestuum 8.80 W 10.90 N

Sinus Aestuum (Bay of Billows) is a mare-like lowland where its eastern edge is the slopes of Montes Apenninus, 290 km in diameter. Its floor contains concentric wrinkle ridges.

Eratosthenes See [Map 19.

Conon 2.00 E 21.60 N

A prominent crater on Apenninus, 21 km in diameter. Some people guessed it could be an "oversized" secondary crater produced by the gigantic Imbrium impact. A sinuous rille (Rima Conon, length 30 km) is in the vicinity.

Macro Polo 2.00 W 15.40 N

An irregular shallow crater on the southern slope of Montes Apenninus, 21 x 28 km.

Rima Bradley 1.20 W 23.80 N

A prominent linear rille running parallel with Montes Apenninus, length 160 km. Rima Hadley 3.00 E 25.00 N

A sinuous rille which begins at the elongated crater Bêla (2 x 11 km). It is a typical lava channel, 80 km long, 1~2 km wide, 300 m deep. On 1971.07.30, Apollo 15 landed on the eastern side of this rille, near Mons Hadley Delta. See Image T137.

Rimae Fresnel 4.00 E 28.00 N A system of rilles, length 90 km. A closer view is shown in T137. The main rille appears to be a continuation of Rima Hadley. It ends near the spiky cape Promontorium Fresnel.

Montes Spitzbergen 5.00 W 35.00 N A group of adjoined mountains with peak height up to 1400 m, base 60 km.

Archimedes 4.00 W 29.70 N A flooded crater with terraced walls, 82 km in diameter, 2100 m deep. Its large size suggests central peaks once existed, but they were buried by post-flooding of lava on the floor. The ejecta blanket of Archimedes is also buried partially in lava. This makes the crater rim to look bulgy. A prominent triangular cape extends 30 km from the southeast rim.

Montes Archimedes 4.60 W 25.30 N A mountain range adjoining the south rim of Archimedes, length 160 km. It might be part of Montes Apenninus 3.8 billion years ago, before Mare Imbrium was formed.

Rimae Archimedes 4.10 W 26.60 N A broad system of rilles running between the south-east of Archimedes and Montes Apenninus, length 170 km. At least two rilles of the system are recognizable in small telescopes.

Autolycus 1.50 E 30.70 N Aristillus 1.20 E 33.90 N A prominent crater pair in the Apenninus region. Autolycus has a rough floor with disintegrated central peaks, 39 km in diameter. Aristillus has wide ejecta blanket, terraced inner walls and multiple central peaks, 55 km in diameter. A ghost crater is also beneath the ejecta blanket of Aristillus (shown in Image T120, Map 15|.) Both craters are centers of bright rays under high illumination.

In 1959, the Russian Luna 2 probe hit the Moon near Autolycus and Sinus Lunicus (Bay of Luna). Luna 2 is the first man-made object to reach the Moon surface.
