| − | ''([ | + | ''([[IAU%20Directions|IAU Directions]])'' BULLIALDUS.--A noble object, 38 miles in diameter, forming with its surroundings by far the most notable formation on the surface of the [[Mare%20Nubium|Mare Nubium]], and one of the most characteristic ring-plains on the moon. It should be observed about the time when the morning terminator lies on the E. border of the [[Mare%20Humorum|Mare Humorum]], as at this phase the best view is obtained of the two deep parallel terrace valleys which run round the bright inner slope of the W. wall, of the crater-row against which they abut on the S.W., and of the massive E. <u>glacis</u>, with its spurs and depressions. The S. border of Bullialdus has been manifestly modified by the presence of the great ring-plain A, a deep irregular formation with linear walls, which is connected with it by a shallow valley. The rampart of Bullialdus rises about 8,000 feet above a concave floor, which sinks some 4,000 feet below the Mare on the W. With the exception of the fine compound central mountain, 3,000 feet high, there are few details in the interior. On the S., is the fine ring-plain B, connected with the S.W. wall near the crater-row by a well-marked valley, and nearly due W. of B is another, a square-shaped enclosure, C, with a very lofty little mountain on the W. side of it, and a crater on its S. wall. In addition to these features, there are many ridges and surface inequalities, very prominent under oblique illumination.<br /> <br /> |

- The so-called "causeway" across the shallow valley Bullialdus W (which is mentioned by Antonin Rukl on his Chart 53), is noticeable near the lower left corner of Lunar Orbiter 4's photograph LOIV-125-h2. It was also captured near the upper margin of Apollo 16's orbital color-Hasselblad frame AS16-119-19104.
- Terrestrial telescopic color-photographs of Bullialdus, made during (or near) Full Moon, show a curious yellowish coloration at Bullialdus's central peak and floor. This curious color is noticeable in many photographs of this crater, such as the one by Michael Hunnekuhl, in the LPOD Spotted Moon.

(IAU Directions) BULLIALDUS.--A noble object, 38 miles in diameter, forming with its surroundings by far the most notable formation on the surface of the Mare Nubium, and one of the most characteristic ring-plains on the moon. It should be observed about the time when the morning terminator lies on the E. border of the Mare Humorum, as at this phase the best view is obtained of the two deep parallel terrace valleys which run round the bright inner slope of the W. wall, of the crater-row against which they abut on the S.W., and of the massive E. glacis, with its spurs and depressions. The S. border of Bullialdus has been manifestly modified by the presence of the great ring-plain A, a deep irregular formation with linear walls, which is connected with it by a shallow valley. The rampart of Bullialdus rises about 8,000 feet above a concave floor, which sinks some 4,000 feet below the Mare on the W. With the exception of the fine compound central mountain, 3,000 feet high, there are few details in the interior.

The yellowish/reddish coloration of the central peak of Bullialdus
This remarkable coloration is captured on the LROC's WAC albedo/color map, see close up of Bullialdus and environs: http://bit.ly/1CPZxT9

- Note the wonderfully impacted display (yellow box in the large image version below - click image) of lighter material from this WAC view showing a region northwest of Bullialdus B. Did a chunk from Tycho's (to the south-east) ejecta clip the rim; sending out material across the darker ejecta plain of Bullialdus crater?. There also is an additional feature to look out for here just south of Bullialdus crater itself (red box in larger version image), where upto five fingers of lighter-looking deposits (again, possibly due to ejecta material-chunks from Tycho crater) has directionally, and dynamically, aligned itself back to that crater.

- A certain Whitley discovered several chains of minute craters southeast of Bullialdus, see page 136 in T.W.Webb's Celestial Objects for Common Telescopes (Volume 1; The Solar System, chapter THE MOON). - DannyCaes DannyCaes Jul 11, 2015
Nomenclature
- Named for Ismaël Boulliau (September 28, 1605 - November 25, 1694), a French priest, librarian and astronomer. Boulliau's name has apparently also (but incorrectly according to this 19th century French encyclopedia) been spelled Bouillaud. It is for his astronomical and mathematical works that Boulliau is best known. Among them in his Astronomia philolaica, published in 1645 and famous for the passage in which he proposed that the force of gravity follows an inverse-square law.
- According to Whitaker (p. 211), the crater name, in the Latinized form Bullialdus, has continued unchanged since its original use on Riccioli's map.
- Mary Blagg, in her Collated List (1913) noted that the feature name was spelled Bullialdus by Neison, 1876 and Schmidt, but Bulliald by Beer and Mädler (possibly a misprint in her catalog?).
- Curiously, the name is printed and listed as Bouillaud on Sheet 2 of the Army Map Service's LTM series (prepared in 1963), which claims to adhere strictly to the then-current IAU nomenclature. Why the map makers thought the IAU name had been changed to this (incorrect) non-Latinized form is unclear. It does not seem to have been used in that way on any other maps of the period. - JimMosher JimMosher
- I have the 1935 IAU map and catalog where the name appears as Bullialdus; apparently the LTM list is not an error-free transcription. - tychocrater tychocrater Aug 1, 2007
- Why are there no officially recognized names for two pronounced craters south of Bullialdus? (still called Bullialdus A and Bullialdus B). - DannyCaes DannyCaes Apr 29, 2017
