9839 Crabbegat           Discovered 1988 Feb. 11 by E. W. Elst at the European Southern Observatory.
Crabbegat is an idyllic road at the border of the Wolvendael park, close to the Royal Observatory at Uccle. The name might refer to "crab", although Uccle is located near neither the sea nor even a stream.
