We report an optical spectrum of PSN J02004778+1641365 that was obtained on 2015 Nov.03.7 UT with the 2.16-m telescope (+BFOSC) at Xinglong Station of NAOC. The spectrum is consistent with a type Ia supernova at 1-2 weeks after the maximum light. Cross-correlation with a library of supernova spectra using the comparison tool SNID (Blondin & Tonry 2007, ApJ, 666, 1024) shows that it matches with SN 2005kc at t = + 10 days. Adopting a redshift of 0.027 for its host galaxy (from the SNID fit), an expansion velocity of about 10000 km/s can be derived from the absorption minimum of Si II 635.5 nm.
