Ultraviolet and visual wavelength spectroscopy of gas around ETA Carinae

Observational results of Eta Carinae are reported, especially spectroscopy of the outer 'S condensation' supplemented by data on the homunculus and its core. Theoretical calculations of atmosphere/wind models and of the shock-heated S condensation are needed for a proper analysis of the data, but some simplified results are discussed. The helium abundance at the surface of Eta Car appears to be roughly 0.4, and most of the CNO is nitrogen. There does not appear to be any reason, at present, to alter the often quoted temperature estimate of 30,000 K for the radiating surface (which may or may not be the surface of the star itself). The presently observed mass loss rate is probably less than 10 exp -2.4 solar masses/yr if the outflow is not strongly direction-dependent. Finally, a largely forgotten but highly relevant historical conjecture concerning Eta Car is mentioned.
