A single small crater of about 22.6 meters (about 74 feet) in diameter is surrounded by light and dark-toned ejecta - indicating that this impact excavated to a depth where light colored strata exists. The crater occurs near 20.6 degrees north latitude, 356.8 degrees west longitude, in Arabia Terra. Images of the area show how the impact site appeared to the Mars Odyssey Thermal Emission Imaging System infrared instrument before and after the impact.[20]
