The eruptive processes in active region NOAA 3804 (Carrington's rotation (CR) No 1724), studied in Jordan et al. (1997), represent the most energetic events that occurred in the evolution of a large-scale activity complex that formed over a period of nearly two years during 1981 - 1982. Three rotations after the July 9, 1982 event, the magnetic configuration of this complex changed rapidly. Only two rotations later it was gone, and had been replaced by a large distinct coronal hole in the same area of the solar surface. Here we describe the evolution of this complex before, during and immediately following the phase of maximum activity.
