A Complex of Three Spot Groups with Only a Few Flares and X-Ray Events
The complex composed of three sunspot groups in the last ten days of May in 1980 were optically observed at Yunnan Observatory. There was a complex configuration in these spot groups, but only a few flares and x-ray events occurred. The morphology and the evolution of this complex of the spot groups are described.
