On the map we see the southeastern edge with its countless dark spots, that characterize Mare Australe. This Mare is circular, as pictures taken by for instance Lunar Orbiter have shown us. The diameter of Mare Australe is about 900km, and it is clearly an ancient Moon basin.
MARE AUSTRALE - The "Southern Sea”. Irregularly shaped Moon Mare extending to the backside of the Moon.
Crater. (46km/27Mi ř ) (49.1°S, 68.5°E) Circular formation. Few steep slopes supporting Peirescius D to the North and Brisbane E to the South-East. Few high walls supporting a craterlet to the North-East. Flat floor.
HANNO - Hanno II of Carthage. The Navigator. (Chanan חנן - Merciful) (Born about 500 BC, Carthage) Navigator from Cathage, north Africa. Discoverer. Sailed westwards through the straits of Gibraltrar, and than south along the west coast of Africa. Later King of Carthage.
Crater ( 58 km/34Mi ř ) (56.3°S, 71.0°E) Heavily worn crater formation with an outer rim that has been battered and pock-marked by small impacts. A small crater attached to the north-northeastern rim forms a depression in the side. The inner walls are nearly featureless except for a few small craterlets, and the interior floor is likewise level and battered by tiny craters.
LYOT - Bernard Ferdinand Lyot. (1897 - 1952) French Astronomer. Inventor of the coronograph in 1930 and the monochromatic filter in 1933. Observer of the Sun and planets. Member of the French Academy of Sciences in 1939.
Crater. ( 145 km /85 Mi ř ) (50.2°S, 84.0°E) Walled plain filled with lava situated in the zone of librations. Few steep slopes supporting many craters to the South-West and Lyot A & C to the West. Few high walls crushed by Lyot F and N to the South. Immense dark circular shaped flat floor, supporting Lyot D & E to the South and Lyot B to the West. Craterlets. Collapsed edge.
PETROV - Evgenij S. Petrowitch Petrov ( Евгений Петрович Петров ). (1900 - 1942 Russia) Russian rocket specialist and engineer.
Crater ( 51Km/30 Mi ř ) (61.4° S, 88.0° E) Circular formation situated in the zone of librations. Steep slopes. Few high walls. Flat floor. The rim of this crater has been worn and eroded by impacts, leaving an irregular ring of ridges and incisions along the inner wall. The smaller crater Petrov A intrudes slightly into the southern rim. Along the southeast, Petrov B is attached to the southeastern exterior and the two are joined by a narrow valley.
Crater (94Km /55 Mi ř ) (58.7° S, 66.0° East) Circular formation. Steep slopes supporting a crater to the South and Pontecoulant A to the North-West. High walls with terraces.Flat floor with a craterlet to the North-west.
STEINHEIL - Carl August von Steinheil. German Physicist. (Born : Ribeauvillé in 1801 - Died : München Germany, 1870) Constructor of first public telegraph in 1838. Manufacturers of optical instruments and the large astronomical lenses.
Crater. (70Km /41Mi ř ) (Dept: 3,000m /9,100ft) (48.6° S, 46.0°) Circular formation forming a remarkable couple with Watt. Steep slopes supporting two craters to the North and overlapped by Watt to the South-East. Very high walls with terraces supporting a craterlet to the South. Flat floor filled with lava. Wrinkles ridges and crevices.
WATT - James Watt. scottish Engineer. (Born: Greenock, Scotland in 1736 - Died: Heathfield, Scotland in 1819). Works on the vaporization of the water. Improved the steam ingine. Inventor of the regulator and the condensor.
Crater. (68Km /40Mi Ř ) (Dept: 3,000m /9,100ft) (49.5° S, 48.0° E) Circular formation forming a remarkable couple with Steinheil. Steep slopes overlapped by Steinheil to the North-West and supporting Watt A and R to the South-West and Watt C to the South-East. High walls with terraces. Battered floor with a craterlet to the South-West.
