We report an optical spectrum (range 330-900 nm) of PSN J02330480+3530396 that was obtained on Mar. 17.5 2015 UT with the 2.4-m telescope (+YFOSC) at LiJiang Gaomeigu Station of YNAO. The spectrum is consistent with that of a type Ia supernova at around the maximum light. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) shows that it matches with SN 1994S at t = +1 days. Adopting for the host galaxy a recession velocity of 13491 km/s, we measure a velocity of the Si II 635.5-nm absorption feature as about 11000 km/s.
