The intense microwave burst associated with a white light flare on 1991 June 6

This paper briefly reports on the intense microwave burst associated with a white light flare at 2545 and 2645 MHz on 1991 June 6. The burst had a very high flux density, a very high degree of polarization and very complex changes in polarization state. A chromospheric white light flare was observed during the first peak of the burst. We briefly discuss the time relation between the two and the cause for the changes in polarization.
