Sinus Meridiani

Sinus Meridiani (LatinSinus meridiani, "Meridian Bay") is an albedo feature on Mars stretching east-west just south of the planet's equator. It was named by the French astronomerCamille Flammarion in the late 1870s.

In 1979-2001, the vicinity of this feature—with size about 1,600 kilometers (990 mi) and coordinates of the center 7°07′S4°00′E / 7.12°S 4°E / -7.12; 4—was named Terra Meridiani.
