Abstract
Results are discussed for low-resolution uv observations of the symbiotic star CH Cyg and of the eclipsing binary VV Cep during chromospheric eclipse following totality. The far-uv and absorption-line spectra of CH Cyg and VV Cep are found to be remarkably similar. It is shown that the energy distribution for CH Cyg is very similar to that of an A0 V star and that the energy distribution for VV Cep is similar to that of an A0-A2 star. Evidence is cited for an extended envelope surrounding the M supergiant component of VV Cep, and an absolute visual magnitude of about -2 is estimated for this system.
