Observations of G 320.4-1.2 and speculations of supernova remnant morphology.

The results of 843 MHz scans of the supernova remnant (SNR) MSH 15 - 52 are reported. The maps were made in 1982 and supported the concept that the SNR contains a pulsar component (1509 - 58) as do the Crab and Vela SNRs. MSH 15 - 52 may be dominated by two diametrically opposed beams emitted by the rotating pulsar. Synchrotron emissions arise where the beams intersect high density regions. The pulsar may have the same orientation as the Vela pulsar, i.e., both may emit radio and X-ray beams that travel along the axis of sight of the observer.
