Abstract
The symbiotic nova RR Telescopii has been observed with the 3.9 m telescope at the Angle-Australian Observatory (AAO), using the University College Lo ndon Echelle Spectrograph (UCLES) in conjunction with a Tek CCD. It display s a rich emission line spectrum, ranging in excitation from NI to [NiVIII]. We present a list of 811 measured lines, with their suggested identificati ons and absolute line intensities, covering a wavelength range from 3180 An gstrom to 9455 Angstrom(1). The absolute line intensities have been derived by comparing the high resolution data with a flux-calibrated low resolutio n spectrum taken with the Australian National University 2.3 m telescope. A ll of the lines have been successfully identified. Comparing our results wi th those of previous studies indicates that the RR Tel system is advancing to-wards higher degrees of ionisation.
