RS Ophiuchi (RS Oph) is a symbiotic variable and a recurrent nova (RN). We have monitored it with the Nordic Optical Telescope and obtained 30 high-resolution (R = 46 000) optical spectra over one orbital cycle during quiescence. To our knowledge, this is the best-sampled high-resolution spectroscop...
