1988 International Astronomical Union Colloquium  
This slow nova has been observed spectroscopically at Observatoire de Haute-Provence in two wavelengths regions: 330–460 nm (plate factors: 4 and 8 nm), and 750–1100 nm (plate factors: 23 and 26 nm/mm).Time coverage includes the following stages: close to maximum of light, early nebular phase and advanced nebular stage.Spectra are similar to those of classical novae: strong continuum, wide emission bands with double structure, flanked by a moderate strength absorption component at −1400
