Abstract

Measurements of spectrograms of RS Oph taken 110 days after the 1967 outburst are reported. Wavelengths, identifications, and intensities are presented.A continuum is present with a spectrophotometric gradient equivalent to that of a K0 star. Weak absorption lines confirm the presence of a cool source or a cool shell. The radial velocity of the emission lines is — 47 km/sec and the absorption lines is — 54 km/sec, neither of which differs greatly from velocities observed between outbursts.
