Abstract
Low-resolution spectra, taken at La Silla (ESO), identify the old nova RS C ar (1895) as a similar to 18 mag star located 7 arcsec southwest from the p revious published position. This suggests a much brighter absolute magnitud e of the old nova, M(v)similar to5.4, than previously suspected. The spectr um reveals a continuum energy distribution typical of optically thick accre tion discs and quite a high excitation state of the gas. The possible detec tion of the AlO lambda 4843 emission band is discussed.
