Spectrograms of the variable star RW Aur at 168- and 48-A/mm dispersion were obtained in the autumn of 1975 with the 50--inch Crimean reflector, equipped with a single-stage image converter. Lines of Ca II, O I, N I, Ti I, Fe I, and H I have been identified in the 0.80--0.94 ..mu.. wavelength range. Spectrophotometric analysis has yielded relative intensities of the Ca II and O I emission lines, and profiles and halfwidths for the lines of the Ca II triplet. A comparison is made with data for the variables T Tau, RY Tau, and Ab Aur. The spectrum of RW Aur in the neighborhood of the infrared Ca II triplet resembles the spectrum of a prominence on the quiet sun observed in May 1963.
