The sample is angular and is approximately 7.0x6.5x5.5 cm. This appears to be a whole specimen, with the exception of a 3.0x4.0 cm area, which has been chipped away. A dull, black fusion crust covers approximately 30 to 40 percent of the sample. The portion of the sample not covered with fusion crust is weathered reddish-brown. A yellowish-brown clast ~0.5 cm in diameter was observed on the W surface.
