The Murchison Widefield Array (MWA) is a low-frequency precursor telescope to the Square Kilometre Array (SKA), developed by an international consortium and located near Boolardy Station in Western Australia, at the Murchison Radio-astronomy Observatory (MRO) which offers a radio-quiet environment and stable climate for observations.
The MWA project acknowledges the traditional owners of the MRO, the Wadjarri Yamatji people. The project is being undertaken with the permission of the Wadjarri Yamatji people, governed by an Indigenous Land Use Agreement (ILUA). We deeply appreciates the trust the Wadjarri Yamatji place in us in undertaking this work on their land.

Electronics equipment from Fremantle-based Poseidon Scientific Instruments (PSI) will help humanity look 13 billion years into the past.
PSI has delivered the first production-ready receiver for the Murchison Widefield Array (MWA) radio telescope to the International Centre for Radio Astronomy Research (ICRAR).

We present the first spectroscopic images of solar radio transients from the prototype for the Murchison Widefield Array (MWA), observed on 2010 March 27. Our observations span the instantaneous frequency band 170.9-201.6 MHz. Though our observing period is characterised as a period of 'low' to 'medium' activity, one broadband emission feature and numerous short-lived, narrowband, non-thermal emission features are evident. Our data represent a significant advance in low radio frequency solar imaging, enabling us to follow the spatial, spectral, and temporal evolution of events simultaneously and in unprecedented detail. The rich variety of features seen here reaffirms the coronal diagnostic capability of low radio frequency emission and provides an early glimpse of the nature of radio observations that will become available as the next generation of low frequency radio interferometers come on-line over the next few years.
