06.Strabo

On the chart the northeastern edge of the Moon, and parts of Mare Frigoris.   To orientate ourselves we use the crater pair Strabo and Thalus, and the three Strabo craters.

BAILY - Francis Baily. (1774 - 1844) English Entrepreneur who after 1825 concentrated on astronomy alone. Discovered "Baily's beads" The well know phenomena of sunlight playing with the edge of the moon during a Solar eclipse.

Crater- (27 km /16 Mi ) (49.7N, 30.4E) Broken wall. In the south-east partially broken formation, steep slopes, high walls supporting an incomplete crater to the north-east and damaged in the south. Flat floor. Central rille.

CUSANUS - Nilolaus Krebs (Chrypffs) (1401 - 1664). Roman-Catholic philosopher, theologian and cardinal. German. He recognized the Earth is a globe and was against Geocentrism.

Crater - (63 km /38 Mi ) (72.0N, 70.8E) Floor flooded with lava. Circular, steep slopes, high walls supporting two craterlets to the East, Flat floor.

DE LA RUE - Warren de la Rue. (1815 - 1889) English physicist, and astrophotography pioneer.

Crater. (136 km /82 Mi ) (59.1N, 53.0E) Eroded walled plain. Damaged steep slopes supporting Strabo to the north. Dislocated walls. Flat floor supporting De La Rue I and a large craterlet to the center. Lines of crests, cracked hills and craterlets.

Mare Frigoris - Sea of Cold. Named by Giovanni Riccioli, (1651) Moon Seas.

Sea (1,446 km /899 Mi ) (56.0N, 1.4E) (436,000 km ) Lengthened west-east, irregular formation. Very dark lava.

GRTNER - Christian Grtner. (About 1750 - 1830) German mineralogist and geologist, telescope maker and astronomer, noted for his observation of   the 1758 return of Halley's comet.

Crater. (105 Km /62 Mi ) (Depth: 1,300 m) (59.1N, 34.6E) Remains of a Walled plain. Halve circular formation with steep slopes supporting Grtner A  to the north-east and Grtner G and F to the east. High walls flooded by lava   to the south in Mare Frigoris. Flat floor filled with lava. Grtner D to the south and Rima  Grtner to the East. Hills and craterlets.

HAYN - Friedrich Hayn. (1863 - 1928) German Astronomer. Improved the theory on the rotation of the Moon. Mapped the edges of the Moon

Crater. (90Km/53Mi ) (64.7N, 85.2E) Western inner side is permanently hidden from sight. Observation of this crater is affected by libration, which can completely hide this crater from sight. This crater lies across the northwestern rim of the walled plain Belkovich, to the north of the Mare Humboldtianum isolated from other craters, the nearest being Cusanus. Not much eroded, circular, uneven rim and an inner wall with terraces. The southern rim joins the eroded rim of Belkovich. The interior flat floor has several ridges that lie near  the interior midpoint. Valleys, peaks, smaller hills, central peaks.

SCHWABE - Samuel Heinrich Schwabe. (1789 - 1875) German Astronomer, Discoverer of the 11 year cycle of the appearance of solar spots.

Crater. (25km/15Mi ) (65.1 N, 45.6 E) Lava covered floor. Irregular shaped formation. Steep slopes to the east. High walls, partially missing to the west. Flat floor.

STRABO - Strabon. (Στράβων) (About 63 BC - 19 AD) Greek historian   and Geographer. His book "Geographia" has been preserved. It is still one of  the most important Works of its kind brought to us from the Ancient World.

Crater. (55km/33Mi ) (61.9 N, 54.3 E)  Prominent crater. Steep slopes supporting Thales to the west, terraced walls and a lava covered flat floor, showing a craterlet to the East.

THALES - Thales of Miletus.(Θαλῆς ὁ Μιλήσιος) (About 625 - 545 BC) Mathematician, founder of Greek land surveying, materialist, philosopher. Calculated the solar eclipse of 585 in advance. Theory of water being the founding principle element of the world.

Crater. (32 km /19 Mi ) ( Depth: 1,800 m) (61.8N, 50.3E) Clear and sharp edged circular crater. Rays. Steep slopes supporting Strabo to the east. High walls with terraces, flat floor.
