Scientific paper

Spectroscopic observations of the peculiar Object Kuwano (Nova Vul 1979) from August 1979 to October 1980 are reported. During the 1979 maximum the spectrum matched an overluminous F star. During the phase of rapid decline the F absorption spectrum was replaced by that of a late M giant with H-alpha and Na I D emission. During the prolonged minimum around JD 2 444 500 emission developed in the N II, O III forbidden lines. The identified lines are listed, radial velocities are estimated, equivalent line widths are estimated, and the intensity jumps at the molecular band heads are measured.
