Descripción
Coordinated multifrequency observations of the dwarf nova SS Cygni have been performed for several years in order to study the accretion behavior of this system in particular and in general to clarify this crucial problem for cataclysmic variables. From IUE measurements, together with those from optical and IR ground based telescopes, orbital modulations in the continuum and in the equivalent widths of the emission lines have been found. During quiescent phases the behavior of SS Cygni is dependent on the type of the preceding outburst (long-type or short-type).
