Description
Over the past decade the MWA has established itself as the leading instrument for high fidelity and dynamic range spectroscopic high time resolution images at low radio frequencies. These unprecedented images have enabled a wide variety of solar science, especially for detailed studies of the brightest and faintest active emissions. More recently the MWA solar group has been developing polarimetric imaging pipelines tailored for solar observations. Our first principles approach to polarimetric calibration, in conjunction with the high signal-to-noise solar observations are yielding solar radio images with unprecedented polarization purity. These images are in turn not only enabling more sophisticated analyses and better constrained model parameters for some of the anticipated applications, but also to unexpected discoveries, most notably of the presence of linear polarization during a variety of active solar emissions. We are in the process of initiating a coordinated observing campaign with PROBA-3, a technology demonstration space mission which will offer high quality coronagraph images in the range from 1.1 to 3.0 solar radii. The lower part of this range has only rarely been observed due to instrumental limitations, but is exactly the region where solar radio emissions in the MWA range arise. This talk will present an overview of solar, and some aspects of heliospheric science being pursued with the MWA along with plans for the near future.
