Scientific paper

Strong Balmer and Fe II emission lines with complex structure, together with two P Cyg-type absorption systems at about -850 km/sec and -500 km/sec and wings that extend to + or - 1000 km/sec, are noted in the visible range spectra at maximum of Noca Centauri 1986. In the subsequent nebular phase, strong and broad permitted and forbidden emission lines are noted to have developed a saddle-shaped profile. The characteristics of the nova, which is estimated to be 0.92 + or - 0.02 kpc distant, are noted to resemble those of DQ Her.
