Abstract
A lunar occultation of the Crab Nebula was observed at X-ray energies above 15 keV by a scintillation
counter on a Skylark rocket launched from Spain on 1974 October 7. The angular extent of
the region of emission of 75 percent of the total flux between 15 and 150 keV (average photon energy
39 keV) along position angle 263° is found to be 110" ± 25". The offset of the centroid of the extended
source is such that its projection to the west of NP 0532 is 8" ± 6". The variation of size with
energy, as found from this and other measurements, sets constraints on models for energy transfer
along magnetic field lines in the Crab.
