H., Jr. Abstract Lunar occultations of the radio sources CTA 21, 3C 17, 3C 132, 3C 444, and the Crab Nebula have been observed at a frequency of 950 Mc/s with an 854oot paraboloid antenna. Each immersion or emersion provided a one-dimensional brightness distribution of the occulted radio source, the limiting resolutions varying from 2 to 20 arc sec according to the size and strength of the source. The position of the point source CTA 21 has been determined to within 1 arc sec; positions to within 8 arc sec and some limited structural information have been derived for 3C 17 and 3C 132. Two-dimensional contour maps have been constructed for 3C 444 and the Crab Nebula.
