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