Accurate positions have been measured at Parkes for 451 40 radio sources between declinations 4� and 20�. For most of the sources the r.m.s. uncertainty is � ION arc in each coordinate. Optical identifications are suggested for 94 sources, of which 22 are galaxies and 72 are possible quasi.stellar objects.

Modifications to the Parkes interferometer are described which allow synthesis observations to be made while still retaining the flexibility of frequent baseline changes. Details are given of the receiver with a phase stabilizing device and its performance, on-line computer control, and data processing. Preliminary observations with a resolution of l' of the two sources PKS 2152-69 and 2356-61 and possible optical identifications are discussed briefly.

Optical Identifications

SummaryThree radio identification programmes are described which are drawn from radio samples with accurate radio positions (< 2" arc rms). Optical identifications are being made on the basis of radio-optical positional coincidence alone, without regard to colour or morphology, using the UKST IIIa-J sky survey to a limiting magnitude of 22.5. Some preliminary results are presented.
