The decametric observations of the lunar occultation of Crab Nebula on december 2, 1982.

Observations of the Crab Nebula obtained at 12.6, 14.7, 16.7, 20, and 25 MHz with the N-S antenna of the Ukrainian UTR-2 radiotelescope during the lunar occultation of Dec. 2, 1982, are reported. Occultation curves, brightness-temperature profiles, and a table of positional coordinates are provided. A compact low-frequency source is located at the position of the pulsar NP 0532, confirming the 1974 occultation observations of Bovkun (1979); the boundaries of the NW and SE emission zones are determined; and the contribution of the NW region to the total nebula emission is found to decrease from 22 percent at 25 MHz to 10 percent at 14.7 MHz.
