Abstract: Quantitative measurements of magnetic fields in flares and CMEs are critical to understanding both phenomena. In this paper we briefly explore the use of radio observations to measure coronal fields. While several radio diagnostics exist, we focus on gyrosynchrotron radiation from energetic electrons in the source. It is shown that with broadband imaging spectroscopy at decimeter and centimeter wavelengths, the magnetic field can be extracted from the data along with a number of other important physical parameters. It is expected that coronal magnetography will be a key new capability of the Frequency Agile Solar Radiotelescope (FASR), an instrument currently under development.
