RADIO EVENTS GENERATED IN ESPECIALLY LARGE ACTIVE REGION AR5395

This paper briefly introdues observational results with 10 ms time resolution at 3.2cm-λ during the sixth solar-terrestrial-spacial joint observation on March 8-19, 1989 in the Departmant of Astronomy, Nanjing University.The six outstanding events with time structure in second and millisecond scale have been morphologically and statistically analysed. We found that there were fast fine structure in solar outstanding bursts. The fast fluctuations in their morphology are similar to those of millimeter waveband emerge.
