Abstract
The size of the hard X-ray source in the Crab Nebula was observed with scintillation counters on board two balloons at a lunar occulatation on 24 January, 1975. The Gaussian width of the source is 34" (+17", -14") and the center thereof is offset from the pulsar by 6" ± 4" at position angle 102°. The observed time profile can also be fitted to an alternative model of two line sources whose intensities are 48% at 11" and 25.5% at 7" on both sides of the pulsar.
