The results are given of observations of the occultation of the Crab nebula by the Moon at the frequencies 960, 750, 178, 128 MHz. The observations yield the coordinates of the centroids and the angular dimensions of the nebula in the directions of the minor and major axes. Details of the structure of the source at 960 and 750 MHz, for which the occultation curves have the best signal-to-noise ratio, are investigated.
