Sinus Amoris (Moon)

"Bay of Love"

Sinus Amoris extends northward from the northeast end of the Mare Tranquillitatis. Near the southern end of the bay where it outlets into the Mare Tranquillitatis lies the crater Theophrastus. Along the western side is the flooded crater Maraldi and Mons Maraldi. (wikipedia entry)

A sinus is a small plain. On the Moon they are named after latin terms describing weather and other abstract concepts.
