Abstract
The Sydney University Stellar Interferometer (SUSI) is a long baseline optical amplitude interferometer. In its initial configuration it is a two aperture, single ro instrument with wavefront-tilt corrections and dynamic optical path length compensation. It has been designed to measure the angular dimensions of stars of essentially all spectral types as well as the angular separations of binary stars. SUSI is located alongside the Australia Telescope at the Paul Wild Observatory, near Narrabri in northern New South Wales, Australia. It has a North-South array of input stations giving baselines covering the range from 5 m to 640 m. The baselines are being progressively commissioned, starting with the shorter ones, in parallel with an observing program aimed at fine-tuning the performance of the instrument. Progress and results from the commissioning program and the current status of the instrument are described.Keywords
