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 2100 km s-1, although an early Hα profile showed a weak feature at -3500 km s-1, 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 ([CITE]). Interstellar lines and bands, as well as BV photometry taken from the literature yielded to a fairly high reddening of . The visual light curve was used to deduce MV by the maximum magnitude versus rate of decline relationship. The resulting parameters are: , days, days, . Adopting these parameters, the star lies between 3 kpc and 8 kpc from the Sun.
Key words: stars: novae, cataclysmic variables / stars: individual: V2275 Cyg
