		Draw a sketch of the crater and the mountain in the center of the crater, and any other features that may be physically associated with the crater.
		Crater density and the relative ages of highlands and maria: One of the most important ways astronomers have learned about the moon, the history of the earth, and the history of the entire solar system is by ``crater counting,'' i.e.
		For example, a crater at the center would be at a distance of 0, a crater halfway between the center and the limb would be at 0.5 and one right on the edge would be at 1.0.

		The small triple crater comprised of Vogel, Vogel B, and an unnamed crater adjoining Vogel to the south, may serve as a landmark.
		I located a sunrise ray while observing the crater row Halley, Hind, Hipparchus C, and Hipparchus L. The ray was located to the southeast of the crater Hind and originated from an unnamed crater or depression at latitude 9.5 deg.

		There is a small crater in the northwestern wall of Theophilus called Theophilus B and is only 4 miles in diameter.
		Cyrillus, named for a 5th century Greek Philosopher, is the similarly sized crater to the southwest of Theophilus.
		Actually there are many craters associated with Catharina and all given sub-Catharina names like Catharina B etc. The crater Catharina was named after Sainte Catherine d’Alexandrie.

		Craters, impact basins and especially their ejecta deposits were excellent markers to distinguish between older and younger deposits and in this way unravelling the sequence of events making up the Moon’s geological history.
		Crater Archimedes for instance is filled and surrounded by lava, meaning that it is older than the surface lava floods of Mare Imbrium.
		Eratostenes as an example of large craters which are formed after the period of major lava extrusion but which are old enough to have their ray system faded away.

		It lies in a rugged stretch of land between the Rupes Altai scarp to the west and Mare Nectaris in the east.
		To the west-northwest is Tacitus crater, and the lava-flooded Beaumont crater lies to the east along the shore of Mare Imbrium.
		With the large Cyrillus and Theophilus craters in the north, it forms a prominent grouping that is framed by the curve of the Rupes Altai.

	NexStar 50 Lunar Club Observation Log - Ken Munson
		Crater to the southwest, Cyrillus, appears to be older as it has at least one good impact crater on its floor and the walls appear more eroded, probably from small impacts.
		The crater appears to have been flooded with later flows, almost to the height of the crater rim.
		Shickard is a big crater to the northwest of Bailly and it has a distinctively dark floor with a band of bright material across the middle.

		In addition to Cyrillus showing a lack of sharpness, it is obvious that the Theophilus impact destroyed a section of it's walls.
		Moving south from the crater Cyrillus we find our third member Catharina, which are connected by a large broad valley.
		Catharina is the largest of the three craters and appears severely battered.

		Theophilus is one of the lunar superstars - a magnificent crater that attracts the attention of observers and imagers.
		The peaks of the same size crater Cyrillus (bottom left) are smaller and more rounded, but who knows how much of that may be related to being pummelled by Theo’s ejecta.
		That they splashed back down is obvious from Apollo 16 images that reveal melt ponds caught in hollows immediately outside the crater and on terraces inside it.
