Abstract
SEVERAL observations of the distribution of radio brightness across the Crab Nebula have been reported over a wide range of frequencies1,2,4–6. The results indicate that the distribution, while slightly elongated, has an approximately Gaussian profile. There is some evidence that the angular diameter increases at the lowest frequencies1, but no fine structure has been detected. Kuz'min and Salamonovich6, observing at a wave-length of 8 mm, noted a small source slightly displaced from the centre of the nebula which they ascribed to an independent source of thermal origin.
