Part I: Large-scale emission features visible in soft X-ray photographs from the spectrographic telescope S-054 on Skylab have been superposed on Ha Synoptic Charts for Carrington Rotations 1601 through 1610. The charts identify loop arcades and loop complexes associated with strong magnetic fields, as well as coronal holes and areas devoid of emission loops. Although not adequate for the study of the geometry of individual features, the charts convey a global sense of coronal structure which is often difficult to obtain from individual (disk) images. Part II: Charts of time versus longitude for each of Carrington Rotations 1600 to 1611 depict: (1) Ha importance, brightness, and location of confirmed flares; (2) peak flare x-ray flux 1-8 A; (3) peak flare decimetric radio intensity; and (4) flux of 1.8 to 4.5 MeV protons plotted at their high coronal emission longitude estimated from simultaneously measured solar wind velocity.
