Description
The Murchison Widefield Array (MWA) is a new-technology low frequency
(80-300 MHz) SKA precursor located in the radio quiet Western
Australian Outback. Solar and Heliospheric science are amongst the key
science objectives of the MWA. Its spectroscopic imaging capability
with much higher imaging fidelity than the earlier generation of
instruments make it especially well suited for following dynamics in
solar radio images simultaneously along time, frequency and
polarization axes.
Type II solar bursts are usually associated with coronal mass
ejections and believed to be produced upstream of shock waves driven
by coronal mass ejections (CMEs) in the solar corona and solar wind.
This talk will use the first such burst observed by the MWA to
illustrate the wealth of knowledge which the new generation of low
frequency arrays can provide, and compare the observations to the
expectations based on the present models.
