We present the spectroscopy of nova V2467 Cyg acquired at the Loiano Observatory, Italy, during the first six months after the outburst. We have used the optical spectroscopy to study the physical properties of the ejected material and the photometry to estimate the nova distance. V2467 Cyg is a fast nova, with decline rates by two or three magnitudes Of 7.6 and 14.6 days respectively. The light curve exhibited oscillations during the transition stage. The nova achieved an absolute magnitude at maximum in the range -8.5...-9.1. The distance is in the range 2.6... 3.6 kpc. V2467 Cyg showed ail early appearance of forbidden lines during the transition stage. Its evolution is similar to the behavior of V 1494 Aql. (C) 2009 WILEY-VCH Verlag GmbH & Co, KGaA Weinheim

Abstract
We present the spectroscopy of nova V2467 Cyg acquired at the Loiano Observatory, Italy, during the first six months after the outburst. We have used the optical spectroscopy to study the physical properties of the ejected material and the photometry to estimate the nova distance. V2467 Cyg is a fast nova, with decline rates by two or three magnitudes Of 7.6 and 14.6 days respectively. The light curve exhibited oscillations during the transition stage. The nova achieved an absolute magnitude at maximum in the range -8.5...-9.1. The distance is in the range 2.6... 3.6 kpc. V2467 Cyg showed ail early appearance of forbidden lines during the transition stage. Its evolution is similar to the behavior of V 1494 Aql.
