摘要：
On June 11, 1991, at 8:00-9:30 UT, several flares were observed in the active region 6659 (N38W24). We have studied the time development, fine-structures, spectral features, polarization, and correlation between different wavelengths of each of these events. The data used in the analysis are Metsahovi and Bern microwave data, GOES7 soft X-ray data, and other wavelength information from the Solar Geophysical Data.
