AR5395:PRELIMINARY ANALYSIS OF THE DOUBLE PEAK STRUCTURES OF MICROWAVE BURSTS

The active region AR 5395, which was on solar dish from March 6 1989 to March 20 1989, was extraordinary for its flare production for a complete disk transit and for one of the largest geomagnetic storms on record. It aroused big interests of many people. During this period, we received more than 60 microwave bursts at 2 cm wavelength. We show only a preliminary analysis to the quasi-periodic amplitude oscillations with double peak structures superimposed on the radio bursts on March 9, 11, 13 associated with the flares occurred in the AR 5395 in this paper.
