  Ariadaeus (crater) - Wikipedia, the free encyclopedia
Ariadaeus is a small, bowl-shaped lunar impact crater on the western shores of Mare Tranquillitatis.
It lies to the north of Dionysius crater, and to the west-southwest of Arago crater.
The crater is joined along the northeast rim by the slightly smaller 'Ariadaeus A', and the two form a double-crater.

Dionysius perfected the science and technic of war, favoured poets and philosophers, and was a wise ruler, but he was suspicious and cruel.
He was succeeded in 368 by his son Dionysius II, a vicious young man, upon whom his uncle Dion and Plato in vain attempted to exercise a beneficent influence.

 LATIUM - LoveToKnow Article on LATIUM
The two main areas near Rome are formed by the group of craters on the north (Bracciano, Bolsena, andc.) and the Alban Hills on the south, the latter consisting of one great crater with a base about 12 m.
The fourth period is that in which the various subaerial agencies of abrasion, and especially the streams which drain the mountain chain of the Apennines, have produced the present features of the Campagna, a plain furrowed by gullies and ravines.
On the southern underfalls of the Alban mountains, commanding the plain at the foot, stood Lanuvium and Velitrae; Aricia rose on a neighboring hill, and Corioli was probably situated on the lower slopes.

Following Gene Shoemaker's analysis in the late 1950s we now know that crater rays are pulverized ejecta widely dispersed from craters formed by high speed impact and mixed with local material gardened by such ejecta.
The two most important recent studies are The Origin of Lunar Crater Rays by Hawke and colleagues, and Optical Maturity of Ejecta from Large Rayed Lunar Craters by Grier and colleagues.
Although there are obviously many rayed craters, lists of crater ray systems are not as common as they were 100 years ago.

There are 5 craters on the floor that progress perfectly from smaller to larger and form a crescent shape starting at the bottom of the main crater.
The larger crater appears to have a fairly smooth peak in the center but none was visible on the smaller of the two craters.
Date Observed: 8/3/02 AM Comments: Although this crater is near the horizon and was somewhat difficult to see, it appears to be the mid-sized crater in a group of 3 similar-sized craters which form a triangle.

 CRATER TIMING REDUCTIONS - 1997 MARCH 24 LUNAR ECLIPSE   (Site not responding. Last check: 2007-11-06)
I could distinguish three differently illuminated regions, the bright uneclipsed north-east cap (5 % of the moon's disk), a central greenish band (50 %) and a reddish band on the south-west of the moon's disk (45 %).
This eclipse probed the moon's artic region and consequently many crater contacts occurred at larger position angles on the umbral edge.
In addition, variation in the ozone and cloud cover at high northern latitudes of the earth may have significantly affected the observed radius of the umbra.

The crater floor looked uniformly dark at first, but on closer observation, particularly under lower powers where contrast was greater, variations in albedo and light intensity could be seen.
In the southwest corner of the crater floor a narrow arc like line could be seen projecting into the interior of the crater from the margin of the dark floor.
The crater floor became considerably lighter towards its junction with the wall in the north.

 Zero by Dick Teresi < mirror < 4umi
The monk was Dionysius Exiguus (roughly translated, "Denny the Runt"), who chose his name out of humility rather than because of small physical stature.
Dionysius was using the Alexandrian method to calculate his own Easter tables when the thought struck him that he was living in the 525th year since the birth of Christ.
If Dionysius and Bede skipped a number, then we must either admit the mistake and correct it or extend the mistake into the next millennium by beginning centuries in the 01 year.

 Observations of Earth's shadow on Moon craters
The timing of craters is useful in determining the atmospheric enlargement of the Earth's shadow.(See Size and shape of the umbra during a lunar eclipse).
If the crater is large enough, it will be possible to measure the times of starting and ending of the ingress (and egress) and then calculate the average for every ingress (or egress).
If the crater is too small then you can take only one measure in the central position of the crater.

Based on the geometry of the graben's sloping walls, the two inward facing faults of the Ariadaeus Rille meet at a depth of 2 to 3 km, which agrees closely with the estimated thickness of the fractured and crumbled ejecta (called the megaregolith) that overlie the deeper, more coherent lunar rocks.
Triesnecker itself is the archetype of a complex impact crater featuring a wreath of slump blocks inside its bright and steep rim.
In the 1940s geologist Josiah Spurr wrote that Triesnecker crater was a volcanic caldera and that the rilles were fractures formed by the upliffing of the surrounding plain as the caldera erupted.
