What is "lubiniezky"

Lubiniezky is a lava-flooded lunar crater on the northwest edge of Mare Nubium. This feature is most readily located by finding the prominent crater Bullialdus to the southeast.

The floor of Lubiniezky has been resurfaced by basaltic lava, which most likely entered from the surrounding mare through the gap in the southeast wall. The surviving rim forms a curved, worn rise around the relatively flat and featureless inner floor. The rim is joined by ridges attached to the north and west walls. To the north of this feature is the bowl-shaped crater Darney. The associated craters Lubiniezky A and E are also flooded, and lie to the northwest.
