Abstract
A visual-region coude spectrogram of Eta Carinae taken in 1981 May is described, and the portion of the spectrum containing Ha is reproduced . This was taken during one of Eta Car's ''abnormal'' stages, which ha ve been suggested by Zanella et al. (1984) to be times of large mass l oss from this unique object. The 1981 spectrum is compared with the '' normal'' spectrum as observed in 1985.
