H. W. Duerbeck, C. Sterken and J. N. Fu, Vrije Universiteit, Brussels, report spectroscopy of V4742 Sgr with the Danish 1.54-m telescope (+ DFOSC) at the European Southern Observatory, La Silla, on Sept. 18.06 UT. The spectrum (range 350-900 nm) shows an Fe II nova shortly after maximum, with a strong continuum and moderately strong emission lines of H, Fe II (multiplets 42, 48, 49, 74), and Na I; the FWHM of H-alpha to H-delta is 2500 km/s. The H, Ca II, and Fe II lines have weak, blueshifted absorption components; the Fe II absorption is split, with sharp components at -1250 and -2100 and broad ones at -4000 km/s.
