Spectra taken at the 1958 outburst of R. S. Ophiuchi have been reduced to units of ergs sq cmsecA and are presented as a function of time for the first month and a half after maximum. The Balmer decrement was constant during the first 3 weeks and agreed well with that found at the 1933 event. The hydrogen lines appeared cut-off on the violet in the early days and an absorption line with velocity around 4000 kmsec was indicated. Many narrow or 1A absorption and emission lines were noted, mostly from and Fe. 0III, NII, and NeIII were seen after about the 5th day. Intensities and half-widths are given for all the lines measured. Author
