Scientific paper

The authors present IUE data of the eclipsing nucleus of NGC 2346 obtained at 3 phases of the 1983 observing season. At φ = 0.02 a highly asymmetric C IV emission line is seen, but the He II line has a gaussian profile with a slight suggestion of an inverse P Cygni character. The stellar continuum in the 1200 - 1950 Å region and high excitation emission lines argue for a hot subdwarf component in the binary nucleus.
