	Bullialdus (crater) at AllExperts (via CobWeb/3.1 planet2.scs.cs.nyu.edu) (Site not responding. Last check: 2007-11-07)
		Bullialdus is a lunar impact crater located in the western part of the Mare Imbrium.
		To the north by north-west is the broken-rimmed and lava-flooded Lubiniezky crater.
		In the center of the crater is a formation of several peaks and rises that climb to over a kilometer in height.

	ST80 Notes: Plato, Bullialdus, Rima Birt
		This small crater was clearly seen at powers from 133x to 190x for a few mintues, then as the angle of light grew higher it completely disappeared, not to be detected again despite repeated attempts.
		The flooded crater Kies was an attractive sight under the low lighting, and the large dome to its southwest quite easily seen in the ST80, though I could only detect a hint of the crater pit reported to occupy its summit.
		Bullialdus F appeared to be surrounded by a softly contoured, dark collar, appearing nearly dome-like and quite different from the commonplace crater drawn by Rukl.

	Ismaël Bullialdus - Wikipedia, the free encyclopedia
		Bullialdus was born Ismaël Boulliau in Loudun, Vienne, France, the first surviving son to Calvinists Susanna Motet and Ismaël Boulliau, a notary by profession and amateur astronomer.
		Bullialdus was a friend of Pierre Gassendi, Christiaan Huygens, Marin Mersenne, and Blaise Pascal, and an active supporter of Galileo Galilei and Nicolaus Copernicus.
		Bullialdus was one of the earliest members of the Royal Society, London, having been elected on April 4, 1667, seven years after its founding.

		Small craters are cleanly visible on the floor and outer ramparts - these could be counted to estimate Bullialdus' age in billions of years.
		But on the NW side of the crater the lava is smooth and uncut by ejecta.
		We have to conclude that the patch of lava NW of Bullialdus is younger than the crater.

		The rims of the crater have the early morning light, while the floor of the crater hangs onto the darkness of night.

	LPOD lunar photo of the day » CRATER CHAINS AND UNKNOWN RILLE
		Wes’ image yesterday showed the area southwest of Bullialdus, and this one is to the east of that crater.
		But I doubt if the chain came from either of those craters - it presumably is from Bullialdus and there must be some bizarre but physically plausible reason to account for it - but I don’t know what that reason is. The real discovery on this image is something you may not yet have noticed.
		It is clearly visible near the small crater Gould X and extends about 25 km to the south where it ends near the mare ridge north of Wolf.

		Agatharchides is a lunar crater located at the southern edge of Oceanus Procellarum, in the region between the Mare Humorum and Mare Nubium.
		To the east-southeast is the Bullialdus crater, and to the south-southwest lies the Loewy crater.
		The interior of the crater has been inundated by lava in the past, resurfacing the floor.

		Bullialdus was a glorious example of a deep lunar crater, lit by the low sun.
		Surrounding the crater walls was a 'shield' or what I thought of as a hood of raised, disturbed, debris-filled land.
		The shadow of the eastern wall cut halfway across the crater, and it made a very nice design.

	Ismail Bouillaud (Bullialdus, 1605-1694) (Site not responding. Last check: 2007-11-07)
		Ismail Bouillaud (or Boulliau, or latinized Bullialdus) was a French librarian, astronomer and priest, who was born in 1605 in Loudun where he studied, then traveling in Italy, Holland and Germany for buying books.
		Because the "nebula" had not been documented by so many famous astronomers, Boulliau suspected that it might been variable, similar to Mira Ceti which he also studied, and attempted to calculate a period of variation - of 333 days, compared to the modern value of 332.
		The astronomical community has named a Moon crater to his honor: Bullialdus (20.7S, 22.2W, 60 km diameter, in 1935).

		If you go further to the south from Copernicus to the next crater visible on the terminator (Bullialdus), you will be crossing three Mares, Mare Insulanum (Rukl 31/42), Mare Cognitum (Rukl 42) and finally Mare Nubium (Rukl 53/54).
		In Mare Nubium, near the terminator the outline of Bullialdus is visible, with Bullialdus A and B just to the south of the crater rim.
		The Lunar surface south of Mare Nubium is heavily cratered.
