Abstract

Z ANDROMEDAE G. Baratta, Rome Observatory; A. Altamore, Rome University; A. Cassatella, European Space Agency, Madrid; and A. Giangrande, O. Ricciardi and R. Viotti, Laboratorio di Astrofisica Spaziale, Frascati, report that new ultraviolet spectra of Z And obtained with the International Ultraviolet Explorer on Feb. 17 showed no significant change in the emission lines. The minimum electron density in the emitting region was 10**9 cm**-3. The optical spectrum, obtained at Campo Imperatore, and the luminosity are still those of the quiescent phase.
