	Pitatus (Site not responding. Last check: 2007-11-01)
		To the south lie the attached Wurzelbauer and Gauricus craters.
		Pitatus is a floor-fractured crater, meaning it was flooded from the interior by magma intrusion through cracks and openings.
		Just to the north of Pitatus in the neighboring maria is the half-buried rim of a lesser crater, covered in the past when Mare Nubium was formed.

	Астронет > Awesome Pitatus
		Pitatus is one of the under-appreciated gems of the Moon.
		Today the crater's rim is heavily battered by later impacts, the terraces are mush, the central peak is still there, and the floor is filled with mare lavas.
		Pitatus is another example of a floor-fractured crater - like Gassendi and Posidonius but its rilles are more concentrated around the floor edges.

	Hesiodus Lunar Ray
		A crater, 28 miles in diameter to the east of Pitatus, with a pass into the latter and with gaps in its north wall.
		On the north is an old ring with a crater and a mountain on the south-east; the wall of the old ring is open on the north.
		To the east of this ring is the crater, B, and on the north a ridge.

		It’s an old, eroded crater with its floor and part of its wall inundated by lunar material that once flowed in a molten state during the formation of the adjacent Mare Nubium.
		Typically, the west wall of Pitatus leaves the floor of Hesiodus partially in shadow, with the exception of a V-shaped patch of light beginning at the opening of the cleft.
		Also note that adjacent to the east wall at the edge of the crater floor is a broken line of little mounds.

		Albategnius (136km) crater is the center of this image.
		The large crater in the shadows is Sacrobosco (98km) which has three prominent craters inside it (13-17km) Two of the craters are obvious, while the third shows only part of its crater lip.
		The Pitatus crater (97km) has a number of of clefs, some of which are evident in this image.

		Pitatus is a battered crater on the southern shores of Mare Nubium.
		It is connected by a narrow valley to the neighbouring crater Hesiodus, which has a small crater (Hesiodus D) at its centre in place of the more-usual mountain.
		The crater Hell is within a much larger crater called Deslandres, most of which is outside this picture.

		The way a lunar crater looks is the result of its formation and all the modifications that have affected it since.
		Perhaps related to the eruption of the lava is the circle of rilles around the inside of the crater walls.
		The final event for Pitatus was the splating of secondary ejecta from Tycho that made the concentrated pits and associated downrange faint rays.

	HesRay
		As the morning terminator crosses the crater Hesiodus, the crater is bisected by a shaft of light coming through a cleft in the wall between it and the adjoining crater Pitatus.
		Since the rim of the crater was also lit, it created a circle of light split precisely in half by a ray of light.
		I was also unsure which crater was Pitatus, though I thought I had it narrowed down to two.

	Hitchhiker's Guide to Rukl Chart 54
		In the shadow of the Straight Wall, the rims of craters Birt and smaller Birt A are prominent circles in stark fl and white contrast.
		Presumably it was in fact a crater at some point, and the wrinkle ridges are all that's left of the west edge of the crater after the rest filled with mare material.
		Approximately as the sunrise terminator crosses the common wall of craters Hesiodus and Pitatus, the rising sun shines through a breach in that wall, and creates a ray of light that very nearly bisects the smaller crater.

	Mare Nubium (Site not responding. Last check: 2007-11-01)
		Alongside this ray on the mare is the crater Bullialdius.
		On the southern edge of the maria is the large flooded crater Pitatus.
		The crater Fra Mauro is situated near the bottom of this tongue, however it does not show up well this close to full moon due to the lack of shadows.

		Copernicus is the large crater near bottom centre, with rays of ejecta clearly visible around it, as are its central peaks and the terraces on its inner slopes.
		The prominent crater Harpalus borders Mare Frigidorum behind Laplace Promontory, while the large crater Anaximenes lies on the terminator near the lunar limb, and the smaller prominint crater Fontenelle lies at the edge of Mare Frigidorum, between Anaximenes and Plato.
		Vitello is the prominent crater with central rise near the bottom of Mare Humorum, and numerous ridges extend across the floor of Mare Humorum from above Vitello to near Gassendi.

	Reports
		This morning I was watching sunset on the southern highlands and noticed a very pretty spoke of light across the floor of Pitatus, running east from the breach in Pitatus' rim where it contacts Hesiodus, directly to Pitatus' central peak.
		The floor of the crater was entirely in shadow except for the thin straight line of light and the starlike central peak.
		Within another fifteen minutes, the southern half of the crater was mostly shadowed with several cone-shaped beams of light visible.

		We have seen that the feature common to all impact craters is, initially, a floor at a lower level than the surrounding terrain.
		It is possible that the crater never had a central peak or it was covered by ejecta from surrounding craters.
		However, in the case of large impacts, the pressure-release accompanying the excavation and rebound of the crater floor, may have been sufficient to initiate the subsequent eruption of material from a pre-existing shallow magma chamber.

		With the 203mm SCT at 200x in the 10mm eyepiece, Pitatus appears as a large crater lying at the edge of a mountain chain on the southern edge of Mare Nubium.
		The crater has a central peak that is just barely visible.
		The floor of the crater has five small bright spots surrounding the central peak.

		Most of these craters were formed between 3,000 and 4,000 million years ago.
		Much of our knowledge of the structure of the Lunar surface and the geology of the Moon comes from the landings of the Apollo series and the samples of Lunar material which were brought back to Earth.

		They were old craters of extinct volcanoes, from which still issued a heated though transparent exhalation, that kept them in an apparently oscillatory or trembling motion, most unfavorable to examination.
		The craters of both these hills, as nearly as we could judge under this obstruction, were about fifteen fathoms deep, devoid of any appearance of fire, and of nearly a yellowish while color throughout.
		Still its head and body differ only in the points stated from that of the beaver, and it was never seen except on the borders of lakes and rivers, in which is has been seen to immerse for a period of several seconds.

		The crater Yerkes was not visible, but there did appear to be a curving cliff that joined up to an isolated peak.
		I think that maybe the Island is a landslide that has broken from the crater wall and settled.

		Off to north side are 7 other craters (not as bright) which are laid out in a curved line.
		There is a double crater (2 overlapping craters) on its south rim and 2 small craters located near the center.
		Comments: About 30 minutes after sunset, Pitatus was fully illuminated and an initial spot of light was observed on the far side of Hesiodus (on top of the crater wall).

	LPOD lunar photo of the day » THE MOON IS NOT GREEN CHEESE
		CAW comment: The rilles of floor-fractured craters like Pitatus probably form in association with an uplift of the crater floor by an intrusion of magma.
		I think that the bright nimbii (plural of nimbus??) around small bright craters are all maturity rays, and rays for very fresh looking larger craters are probably too.
		Maturity is the name for the process of fresh lunar material that is bright from being pulverized and that slowly darkens by solar radiation and cosmic rays.

		I have also included an atlas of the features of the Moon visible from Earth, in case you might someday want to examine the Moon with binoculars.
		(craters toward poles appear bigger due to the projection expanding the smaller polar areas to make a rectangle out of a spherical planet.)

		The astronauts were never here at this time of day, but if they had been, they would have seen the tips of the peaks around them starting to shine with the beginnings of sunrise, while the earth shone high overhead in the night sky.
		The Times Atlas goes as far as the crater "B", and there might be a ridge extending from that crater in the right direction, but so little of it is visible that it's difficult to tell; the atlas doesn't have a page for the area around Riccioli, unfortunately.
		The apparent crater just beginning to peek into the light to the south of Julius Caesar isn't shown clearly at all on Rukl's chart 34; I'm not sure what it is.

		On the southern edge of Mare Nubium is the old walled plain Pitatus.
		Almost central along their shared wall there is a break to watch for when the terminator is close.
		If the terminator has moved beyond it at your observing time, look to the south for small Hesiodus A. This is an example of an extremely rare double concentric crater.

		Once upon a time, it was a very normal crater and remained that way for hundreds of millions of years - then it happened: either an interior fissure opened up, or the impact that originally formed it caused molten lava to seep slowly upward.
		It is a supreme challenge for binoculars to spot, but telescopes of any size at higher magnifications will easily reveal it perched on the terminator in the west-northwest section of the Moon.
		Of course, this crater was named for the man who first contemplated the Moon through a telescope.
