Cerealia Facula, an area in the center of the crater, consists of bright material covering a 6-mile-wide pit, within which sits a small dome.
The spots, forming a bright area called Cerealia Facula at Occator's center and a complex of secondary spots, collectively called Vinalia Faculae, on its eastern floor, appear to be deposits of carbonate-rich salts--residue from briny flows that gurgled up from a fluid reservoir (perhaps a global ocean) deep in the asteroid's interior.
The diameter of the facula was 1-2 [micro]m, and the exposal time of the CCD camera was 10 s.
