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 km/s.The following ions are identified: H I, O I, C I, N I, Mg I and II, Ca I and II, Fe II, Ti II, Si II and Sr II.
