Abstract

We present a series of 8.4-GHz very-long-baseline radio interferometry images of the nucleus of Centaurus A (NGC5128) made with a Southern Hemisphere array, representing a 3.3-year monitoring effort. The nuclear radio jet is ≃50 milliarcseconds in extent, or at the 3.5-megaparsec distance of NGC5128, ≃1 parsec in length. Subluminal motion is seen and structural changes are observed on time scales shorter than 4 months. High- resolution observations at 4.8 and 8.4 GHz made in November 1992 reveal a complex morphology and allow us to unambiguously identify the self-absorbed core located at the southwestern end of the jet.
