A Big Complex Microwave Burst——Solar Radio Burst on Oct. 14 in 1980

A flare of Importance 3B occurred at 0542-0613-0734 UT on 1980 Oct. 14 in a sunspot region (M. W. No 21811, AR2725) at S10/Wl5. During the flare, the spray, it's disturbance along an arc trajectory and the associated radio burst at the 3.2-cm and 10.6-cm wavelengths were observed at Beijing Observatory. The observations of Yunnan Observatory at the 8.2-cm wavelength, Tokyo Observatory at the 2-cm wavelength and Toyokawa at the 15-cm and 30-cm wavelengths, and the spectral data in SGD are used to analyse the the morphology of the microwave burst and the comparisons with Ha and hard x-ray data are given respectively.
