Seleucus is a lunar impact crater located in the western part of Oceanus Procellarum. To the west is the lava-flooded remains of the walled plain Eddington. To the southwest is the crater Krafft and to the northwest lies Briggs.
Struve is the lava-flooded remains of a lunar impact crater. It is located near the western extreme of the Oceanus Procellarum, close to the western lunar limb. As a consequence, even though it is roughly circular in outline, it appears oval due to foreshortening.
Russell is the lava-flooded remains of a lunar impact crater. It is located in the western part of the Oceanus Procellarum, close to the western lunar limb. As a result, it appears oblong-shaped due to foreshortening.
Krafft is a prominent lunar impact crater located near the western edge of the Oceanus Procellarum. To the north is the lava-flooded walled plain Eddington. Almost due south is the crater Cardanus, and the two are connected by a 60-kilometer-long chain of craters known as the Catena Krafft.
Grimaldi is a large basin located near the western limb of the Moon. It lies to the southwest of the Oceanus Procellarum, and southeast of the crater Riccioli. Between Oceanus Procellarum is Damoiseau, and to the north is Lohrmann.
Cardanus is a lunar impact crater that is located in the western part of the Moon, in the western part of the Oceanus Procellarum. Due to its location the crater appears very oval because of foreshortening, and it is viewed almost from the side.
Cavalerius is a prominent lunar impact crater that lies on the western edge of the Oceanus Procellarum lunar mare on the west part of the visible Moon. It nearly joins the northern rim of Hevelius to the south.
Flamsteed is a small lunar impact crater located on the Oceanus Procellarum, which is named after British astronomer John Flamsteed. It lies almost due east of the dark-hued Grimaldi, and north-northwest of the flooded Letronne bay on the south edge of the mare.
Kepler is a lunar impact crater that lies between the Oceanus Procellarum to the west and Mare Insularum in the east. To the southeast is the crater Encke. Kepler is named for the 17th century German astronomer and mathematician Johannes Kepler.
Reiner is a lunar impact crater on the Oceanus Procellarum, in the western part of the Moon. It has a nearly circular rim, but appears oval in shape due to foreshortening. The rim edge is well-defined and has not been eroded by impacts. In the midpoint of the irregular crater floor is a central peak. Outside the rim is a hummocky rampart that extends out across the mare for about half a crater diameter.
Agatharchides is a lunar impact 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 crater Bullialdus, and to the south-southwest lies Loewy. It is named after the Greek geographer Agatharchides.
Balboa is a lunar impact crater that is located near the western limb of the Moon. Due to foreshortening, the crater appears highly oval when viewed from the Earth. In actuality, however, the formation is relatively circular. It is comparable in size to the crater Dalton, located just to the southwest. The eastern rim of Balboa lies just to the west of the Oceanus Procellarum.
Billy is a lunar impact crater that is located at the southern fringes of the Oceanus Procellarum, in the western hemisphere of the Moon. It was named after French mathematician Jacques de Billy. It lies to the southeast of the similar-sized crater Hansteen, and west-southwest of the flooded Letronne.
Briggs is a lunar impact crater that is located in the western part of the Oceanus Procellarum, to the east of the large walled plain Struve. It lies to the northeast of the walled plain Eddington, and north-northwest of the crater Seleucus. The isolated position of this crater on the mare, near the northwestern limb of the Moon, makes it relatively easy for an Earth-bound observer to locate. The crater is named after the English mathematician Henry Briggs.
Bunsen is a lunar impact crater that lies near the northwestern limb of the Moon. It is located to the west of the Oceanus Procellarum and the crater von Braun. To the southeast is the crater Lavoisier, and to the northeast lies Gerard. Northwest of Bunsen, on the far side of the Moon, is McLaughlin. Due to its position this crater appears foreshortened when viewed from the Earth, and its visibility is affected by libration.
Darney is a small lunar impact crater that is located on the region of the Moon where the Mare Nubium joins the Oceanus Procellarum. It was named after French astronomer Maurice Darney. To the south is the lava-flooded crater Lubiniezky. The southern rim of Darney is attached to a series of low ridges that extend to the southwest.
Damoiseau is a lunar impact crater that is located just to the west of the Oceanus Procellarum, in the western part of the Moon's near side. It lies due east of the prominent crater Grimaldi, a walled plain with a distinctive dark floor. Due south of Damoiseau is the crater Sirsalis.
South is a large lunar impact crater that is located in the northwest part of the Moon. Most of the southern wall of this crater is joined to the Sinus Roris bay of the Oceanus Procellarum, with the southeast rim facing Mare Frigoris. Attached to the northwest of the formation is the larger walled plain Babbage. Just to the northeast is the crater Robinson, and farther to the northeast is another walled plain, J. Herschel.
Voskresenskiy is a lunar impact crater that is located near the western limb of the Moon. Due to its position, this crater is viewed edge-on, limiting the amount of detail that can be viewed. The visibility of this formation is also affected by libration, so that at times this crater is hidden from sight, while at other times it can be more readily viewed.
von Braun, named after the rocket pioneer Wernher von Braun, is a lunar impact crater located near the northwestern limb of the Moon. It lies along the western edge of the Oceanus Procellarum, to the northeast of the crater Lavoisier. The northeastern rim of this crater is on the edge of the Sinus Roris, a bay feature in the northwestern part of the Oceanus Procellarum. Due to its proximity to the limb, this crater appears significantly foreshortened when viewed from the Earth.
