 PIA02342: MOC Views of the shadow of the martian moon, Phobos, as captured by the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC). The figure shows wide angle red (left), blue (middle), and colour composite (right) views of the shadow of Phobos (elliptical feature at center of each frame) as it was cast upon western Xanthe Terra over Sabrina Vallis on August 26, 1999, at about 14:00 local time on Mars. The image covers an area about 250 kilometers (155 mi) across and is illuminated from the left. | |

| Naming | an ancient name of a river in England and Wales |
Sabrina Vallis is an ancient river valley in the Lunae Palus quadrangle of Mars and is also in Xanthe Terra, located at 10.99 North and 310.96 West. It is 280 km long and was named after a classical name of a river in England and Wales. The name was approved by IAU's Working Group for Planetary System Nomenclature in 1985.[1] The valley stretches from a large unnamed crater in the west of Xanthe Terra and heads nearly eastward and then a small portion north and finishes just southwest of Lederberg crater at Chryse Planitia at the western rim of Magong.
