Solar Coronal White Light, Fe X, Fe XIV and Ca XV Observations During 1984 : An Atlas of Synoptic Charts

Synoptic observations of the solar corona in white light and in three emission lines (Calcium XV at 5964 A, Iron XIV at 5303 A, and Iron X at 6374 A) were carried out. The observations provide a record of the distribution of the density of the corona as well as the distribution and brightness of the hotter regions of the corona over the year. These data are presented in the form of synoptic maps for each rotation during the year for the purpose of providing a context for the investigations to take place during the Joint Study of Coronal and Prominence Plasmas. In this way, it is proposed both to describe the data coverage achieved and summarize the large-scale properties of the corona in this late descending phase of the solar cycle.
