Abstract:	We present preliminary results from recent HST/STIS observations of the symbiotic binary system EG Andromedae (HD4174) and an isolated spectral standard HD148349 (V2105 Oph). We show the similarities between the red giant primary of the binary system and the spectral standard HD148349 and demonstrate a technique for obtaining contemporaneous low-resolution optical spectra when making UV observations with STIS. We offer new measurements of the differential extinction and brightness ratio between our two target stars as well as a more precise value of the EG And distance. We investigate chromospheric diagnostic emission lines and show how our study of symbiotic stars can be integral to the understanding of mass-loss from isolated red giants.
