Abstract (from CDS):

We present an analysis of low- and medium resolution spectra of the very fast nova, Nova Cygni 2001/2 (V2275 Cyg) obtained at nine epochs in August, September and October, 2001. The expansion velocity from hydrogen Balmer lines is found to be 2100km/s, although an early Hα profile showed a weak feature at -3500km/s, too. The overall appearance of the optical spectrum is dominated by broad lines of H, He and N, therefore, the star belongs to the ``He/N'' subclass of novae defined by Williams (1992AJ....104..725W) Interstellar lines and bands, as well as BV photometry taken from the literature yielded to a fairly high reddening of E(B-V)=1.0mag ±0.1mag . The visual light curve was used to deduce MV by the maximum magnitude versus rate of decline relationship. The resulting parameters are: t0=2452141.4+0.1–0.5, t2=2.9±0.5 days, t3=7±1 days, MV=-9.7mag±0.7mag . Adopting these parameters, the star lies between 3 kpc and 8 kpc from the Sun.
