In photo A: craters Hommel, Vlaq, Pitiscus, Rosenberger, Nearch (76 km) and Hagecius (76 km).

         Nearch (76 km) is an impact crater, situated on the south-east region of the Moon, south-east of the crater Hommel. North of Nearch is Vlacq, and north-east lies Rosenberger. Nearch is 76 kilometers in diameter and 2.9 km deep and dates from pre-nectarian era, now 4.55 - 3.92 billion years ago.
The outer edge of the crater has been affected by small craters, which overlap along the eastern edge. The most important of these is Nearch A (43 km) on south-east edge. Small craters are found on the north and west. The rest of the interior walls are relatively intact, and retains its circular shape.


          Hagecius (76 km), this crater forms a triangle with crater Rosenberger on north-west and Nearch on west-north-west. Like other craters, Hagecius was undergone further erosion of the impacts. South-eastern edge is overlaped by three smaller craters called Hagecius C (24 km), B (34 km) and G (30 km).

In photo C: crater Mutus, Manzinus, Jacobi (68 km), Boguslawsky (97 km), Tannerus (29 km), Kinau (42 km) and Sempilius (70 km).

      Jacobi (68 km), has a margin of several overlapping craters along the southern edge, including Jacobi J (19 km), and a pair on the north side. The result is that the outer edges are flat along the north and south sides. On the north side, Jacobi A, forms a member of a chain of craters, forming a line on the floor inside, from north-east to south-west.

        Boguslawsky (97 km) is located near the southern edge of the Moon. It lies northwest of the crater Demonax, and south-west of Boussingault (131 km). Due to its location Boguslawsky appears elongated.
 Crater floor is flooded and with no many features. The edge is low. Crater Boguslawsky D is on the east side.
The name comes from the Palm (or Palon) Heinrich Ludwig (Pruß) von Boguslawski (7 September 1789-5 Iun 1851) who was a German professor of astronomy.

         Tannerus (29 km). The edge of this crater is almost circular, with only a slight inward bulge along the northern edge where it is joined with Tannerus P (20 km). Edge is clear and well defined, although there are small craters along the border in the west and south. Crater floor is without marks or features.
Crater name is given from Adam Tanner (in Latin, Tannerus) (14 April 1572 - May 25, 1632) which was an Austrian Jesuit professor of mathematics and philosophy.

         Kinau (42 km), is a mile deep. Kinau may date from the pre-nectarian era, 4.55 - 3.85 billion years ago. North-western edge of the crater walls was strongly affected by the impacts, and is overlaid by a pair of small craters, bowl-shaped. The remaining edge is distorted into a hexagonal shape, with the small craters along its rim. The interior walls are relatively low and the interior floor is with almost no characteristics. There is a small rise near the middle of the crater.
The crater is named after 19th century German priest, teacher and amateur astronomer Adolph Gottfried Kinau.

          Sempilius (70 km).  The crater may also date back to pre-nectariana, 4.55 - 3.85 billion years ago.Sempilius was affected by impacts and is relatively circular.The crater is named after Hugh Sempill (or Semple ) (Latin Sempilius) (between 1589 or 1596, and 1654) which was a Scottish Jesuit mathematician and linguist.

To locate craters above, I've described crater names in the picture below, taken on 14/11/2010.

South Moon craters in shadow-Lilius crater

        In this article are photos of Moon craters in shadow from the southern region . Most are presented in other articles, such as Jacobi, Kinau, Zach and Curtius, Pentland and Scott, Sempilius, Schomberger, and Scott.

         Lilius crater (61 km) lies north of the crater Zach, and south-west  of Cuvier. South-east is slightly larger Jacobi. The interior is relatively flat with no features, but there is a high peak on central midpoint.
The crater is named after the inventor of the Gregorian calendar, Aloysius Lilius (1510-1576), also known as Lilio Luigi, Luigi Giglio, or Lilio Baldassare, who was an italian doctor, astronomer, philosopher and chronologist.

List of south features of the Moon-Southern lunar Hemisphere

Southern hemisphere of the Moon is in rough terrain, heavily cratered and with mountainous areas.
At the poles, the sun is always at small angles, so this is creating a unique environment, but also some difficulties in interpreting the geological region.
The southern hemisphere of the Moon craters are very different in size, appearance and how they were formed by impacts in the past.
Personally, the most interesting craters on south, I find Tycho, a crater with rays showing a very high albedo, rays that are left behind from the initial impact, wich can be seen from Earth with the naked eye or binoculars.
Another great crater is Clavius​​, a large crater with other small craters lying inside it in a decreasing order to form a spiral.
Shiller is another crater, interesting to me because of its elongated shape similar to a caterpillar.
 On the southern hemisphere of the Moon seen from Earth, there is only a sea, Mare Nubium that penetrate down to the crater Pitatus.

There are not mountains on the Moon's southern hemisphere. Maybe were probably destroyed by countless impacts were.

Space missions on the south side of the Moon:
Ranger 9 was launched on March 24, 1965 by United States of America and was intentionally crashed on the lunar surface, on crater Alphonsus.
Ranger 9 was designed to achieve an impact trajectory and to transmit pictures of the lunar surface in high-resolution during the flight until the impact.
  Ranger 9 successfully transmitted 5814 images with a resolution of up to 1.5 m.

LCROSS United States launched the LCROSS (Lunar Crater Observation and Sensing Satellite) which was deliberately crashed into the Moon's south pole on crater Cabeus on October 9, 2009
The mission was designed to search for water ice on the lunar surface and examining the resulting cloud, caused by impact. The mission ended with the discovery of significant amounts of water.

Moon Impact Probe was launched by India, and it was deliberately crashed on 14 November 2008 at the lunar south pole.
 It had 35 kg, and was released from Chandrayaan-1 Lunar Orbiter. It was equipped with a video camera, a radar altimeter and a mass spectrometer.

For those who like my astro pictures or my articles, it woul be great if you could pay attention on advertising that appear in the blog by a click and maybe one day I could buy a better telescope.

The southern area into darkness. Images by astronomical telescope.

These images show us the Moon's south terminal with numerous craters. Crater floor we can not study any of these images but only their outer and inner edges, because the Moon terminator does not allow it.

Schomberger (85 km) is one of them which caught my attention because it is totally in shadow and looks more orderly. It is more than a half in dark, being close to the terminator but it can be seen its western interior. However this crater we will not ever be able to see its entire floor from Earth being so close to the edge of the moon, but only partly because it is always observed at oblique angles, with an oval shape.

Other craters visible in these images are Sempilius (70 km), Pentland (56 km), Jacobi (68 km) and Kinau (42 km).

In the picture below are labeled craters and other lunar features in the region. To better understand this photo, you should note that the label with the name or the letter of larger craters could be found at their center, and on the small craters, you should find them around them, usually above.
