(unofficial name; IAU feature name for central 603 km of mare: Mare Australe )
|IAU Lat: 38.9°S, Long: 93.0°E; Basin main ring diam: 880 km, Depth: 2.13 km, Rükl: Libration Zones IV (CURIE) and V (HALE)|
Middle: Aerial view of the basin using LTVT on a Clementine view from Map-A-Planet.
Right: Clementine, the Australe Impact Basin as illustrated by the Clementine LIDAR Altimeter texture from PDS Map-a-Planet remapped to north-up aerial view by LTVT. The dot is the center position and the white circle the main ring position from Chuck Wood's Impact Basin Database. Grid spacing = 10 degrees. This interpretation of the impact basin has a significantly different center from the IAU's Mare Australe.
- Mare Australe as photographed by the crew of Apollo 15: AS15-88-12008. It is one of the last images in Apollo 15's Hasselblad-magazine 88/TT. Note the curious bluish "U"-shaped reflections.- DannyCaes Sep 29, 2013

Note: This feature is not listed in Hartmann and Wood, 1971. The center of the circle appearing in the illustration at the top of this page is placed at 52°S/95°E, which is the center position indicated in the Impact Basin Database. The source of that position is unknown.
- Mare area of 319,000 km^2 according to measurements by Jim Whitford-Stark.
- Rim Height 140 m
- First described as an impact basin by Stewart-Alexander & Howard (1970). The center was given as 44°S/90°E and the diameter as 900 km.
- The IAU official coordinates for the central region of this basin are: - Lat 47.77°S, Long: 91.99°E, Diameter 996.84 km. - JohnMoore2
- The IAU name is Latin for "Southern Sea".
- The impact basin is named for the mare.
- According to Whitaker (p. 219), the name Mare Australe was introduced by Mädler.
- The exact area that is designated by the IAU name is vaguely defined and has changed appreciably over the years. This feature was Catalog Number 4531 in Mary Blagg's Collated List, and its orginal position in Blagg and Müller was apparently 43°S/77°E. In the later System of Lunar Craters, it appears on maps A7 and B8, where it extends roughly from Oken to Hanno, with an apparent center at about 52°S/75°E. Sometime later, the IAU seems to have adopted the positions and diameters listed in Gazetteer of Planetary Nomenclature, which do not necessarily agree with the previous IAU data. The position and diameter listed on the title line are those from the current official on-line IAU Gazetteer. This defines a circle which extends roughly from Abel to Lamb and from Hamilton to Donner. The craters Oken and Lyot fall outside the present boundary. This vagueness of definition and drifting position is similar to that experienced by Sinus Roris. - JimMosher
