Bhonsle, R. V. ; McNarry, L. R. Abstract Polarization characteristics of the Type III solar bursts measured with a narrow-band (10 kc/s), time-sharing radio polarimeter at 74 Mc/s are discussed. It is found that during May-June, 1963, the majority of the Type III bursts were partially elliptically polarized. The 74 Mc/s polarization measurements of the Type III solar radio bursts have been compared with the Cornell 200 Mc/s polarization data. The percentages of polarization and axial ratios of polarization ellipses of the Type III bursts have been found to be of comparable magnitude at 200 and 74 Mc/s. By comparing the Faraday dispersions at these frequencies, the ratio of coronal magnetic fields at 200 and 74 Mc/s plasma levels has been estimated to be 2.8.
