Studies of the Sun from Skylab

The new and exciting contributions to solar physics, which are resulting from the NASA Skylab Program, are reviewed and their broader implications in terms of solar cycle and solar-terrestrial relations are discussed. Among the "active" phenomena studied by the Skylab Apollo Telescope Mount (ATM) solar experiments are coronal bright points, active regions, flares and coronal transient events. One of the most interesting quiet features studied by ATM has been coronal holes. The results of the first Skylab Solar Workshop, which was dedicated to a detailed investigation of these features and of their relationship with the solar wind, are also presented.
