million. The Phase I array was largely driven by the second MWA director, Steven Tingay. In 2017 the telescope received the planned upgrade, doubling both the number of antennas, resulting in an increase in resolution and sensitivity. This upgraded instrument is known as the "Phase II MWA". Phase II was practically completed in October 2017 and officially launched on 23 April 2018. Installation of the additional antennas and commissioning of the array was led by the third MWA director, Randall Wayth and operation of the Phase II instruments have been led by the current director, Melanie Johnston-Hollitt. Science The MWA is an inherently versatile instrument with a very large field of view (on the order of 30 degrees across) able to cover a wide range of scientific goals. In Phase I the array provide a wealth of scientific papers covering topics such as detection of H II region(s) in the Galactic plane, limits on radio emission from extra-solar planets, observations of haloes and relics in galaxy clusters to detection of transient radio sources and space debris tracking. Two of the most significant results from the Phase I MWA were: The first detection of plasma tubes in the ionosphere by undergraduate student, Cleo Loi. Ms Loi won the Astronomical Society of Australia 2015 Bok Prize for her research. The "GaLactic and Extragalactic All-sky MWA" (or "GLEAM") is a survey of 300,000 extragalactic sources at 20 frequencies between 70 and 230 MHz that was carried out by the MWA. Discoveries In January 2022, a team led by Dr Natasha Hurley-Walker of Curtin University re-analysed 2018 GLEAM data and announced in ’’Nature’’ that object GLEAM-X J162759.5-523504.3 is a long periodicity (1,091.170 second / 18m11s) object, that provided a bright pulse of energy for up to a minute, and is some 4,000 light years from Earth in the Milky Way Galaxy. The derived position is in the constellation Norma at right ascension 16h 27m 59.5s, declination −52°35′04.3". The object produces pulses at 154MHz of peak flux densities of up to S154MHz = 45 Jy. Scaling this to 1.4 GHz would indicate S1.4 GHz = 3.5 Jy and, therefore, a luminosity L1.4 GHz = 4×10^31ergs^−1. It is speculated to be similar to a pulsar or magnetar. The object was discovered by Tyrone O'Doherty as part of his undergraduate honours project supervised by Dr Hurley-Walker. System overview An MWA antenna consists of a four by four
