RADIO BURSTS OF VERY SHORT DURATION: FINE STRUCTURE OF SOLAR FLARE EMISSIONS

Abstract

The fine time structure of sub-second radio events of solar flare emissions is described on the multichannel polarimeter of Station Basovizza at 237, 327, and 408 MHz frequencies. We selected the February 8 and July 9, 1982 solar radio bursts, both associated to gamma flares. We considered only events with more than 100 solar flux units. The relationship between the intensity of the impulsive radio events and the background radio emission is discussed.
