The Long Baseline Array is a collaboration between CSIRO, the University of Tasmania, SpaceOps NZ, the South African Radio Astronomy Observatory and CDSCC. Telescopes from these institutions simultaneously observe the same source at the same frequencies using the technique of Very Long Baseline Interferometry, with the data recorded at each site and later correlated at the Pawsey Supercomputing Research Centre. A six-day LBA session is nearing completion, with the wide variety of science being undertaken reflected in the titles of the observing proposals: Resolving the sub-mJy radio source population with wide-field VLBI, Parsec-scale structure of radio sources showing HI-21cm absorption, Testing a new method of Zeeman pair identification using periodically-varying masers, Imaging an OH megamaser in a Compact Obscured Nucleus, Targeted Wide-Band VLBI SETI for Habitable Exoplanets, LBA Astrometric Survey of Millisecond Pulsars at 13cm, Measuring the distance to the middle-aged gamma-ray pulsar B1055-52, Developing a Comprehensive Catalogue of Southern Compact Symmetric Objects, and Physics of Gamma Ray Emitting AGN.
