UTMOST is the results of a substantial upgrade to MOST, the Molonglo Observatory Synthesis Telescope, a radio telescope located in Hoskinstown, Australia. MOST, in turn, was a rebuilding of the Mologlo Cross Telescope. MOST is pair of 778 m cylindrical telescopes stretched out east-west, 15 m separated. UTMOST aims at radio transients including pulsar observations and fast radio bursts. The upgrade which was completed c2017 gave it a modern back end.
