X-ray measurements made during a lunar occulation of the Crab Nebula show that the spatial extent of the source is about 100'' in the east-west direction. The center of the X-ray emitting region is about 8'' west of the pulsar. The shape is basically the same when viewed in several energy intervals from 0.5 to 16 keV. The size does not change by more than 30 percent over this energy range. Optical and X-ray intensity distributions are compared, and no optical features other than the pulsar are obvious in the X-ray data. (AIP)
