Astronomy at the Molonglo Radio Observatory.

A general description of astronomical observation programs at the Molonglo Observatory Synthesis Telescope (MOST) in Australia, is presented. Emphasis is given to completed surveys of HII content and SNR in the Magellanic Clouds. The SNR observations have so far identified 55 remnants which do not conform to conventional theories of SNR evolution. Cataloging and analysis of the HII regions and planetary nebulae data has been completed in the SMC but has only recently been started in the LMC. Other observing programs at MOST include mapping of southern radio and 'normal' galaxies, observations of variable radio sources, 'deep mapping' of a selection of far southern fields for cosmological studies, and studies of the Galactic center. Consideration is also given to advantages of using real-time beams for pulsar studies and for the development of a 'transient event recorder' to search for pulsed or rapidly varying radio phenomena during normal map synthesis. A facsimile of the working map for a standard 70 degree galactic field is given in order to illustrate the observational capabilities of the MOST system.
