Z Andromedae, often considered as the prototype of symbioticstars, experimented, after several years of quiescence, asmall outburst in March–April 1984, followed by a larger onein September–October 1985. The imminence of a new activityphase was predicted by Viotti et al. (1982). Z And is,together with AG Draconis, the only symbiotic star observedboth during quiescence and activity with the IUE satellite.The early photometric and spectroscopic history of Z Andhas been recently reviewed by Kenyon (1986).
