Murchison Widefield Array: Tracing solar disturbances from the Sun to the Earth

The unique and powerful diagnostic capabilities of low radio frequencies for solar, heliospheric, and ionospheric science have long been recognized, but the challenges associated with high-fidelity low frequency radio imaging have limited their exploitation. The Murchison Widefield Array (MWA) is a pioneering new interferometer, currently under construction in the radio-quiet Western Australian outback, which exploits the recent advances in digital signal processing to rise to this challenge. We present an overview of the exciting new solar, heliospheric, and ionospheric science which this instrument will enable, along with early results from a prototype array.
