We report an optical spectrum of PSN J12354442+1606366 (note that the correct coordinates should be R.A.=12h35m44s.42, Decl.=16d05m36s.6, see Transient Objects Confirmation Page of the CBAT) that was obtained on 2015 Feb. 13.9 UT with the 2.16-m telescope (+BFOSC) at Xinglong Station of National Astronomical Observatories of China. The spectrum is consistent with a type IIn supernova, with a relatively blue continuum and prominent narrow Balmer emission lines. The presence of narrow emission features near 500.0nm and 672.0 nm, perhaps due to the O [III] and S[II], respectively, indicates that the supernova spectrum may be contaminated by the light from the host galaxy.
