We report that a CCD spectrum (range 350-1000 nm) of MASTER OT J014638.27+041324.4 (Shurpakov et al., ATel #5630) was obtained on Dec 6.5 UT with the Shane 3-m reflector (+Kast spectrograph) at Lick Observatory. The spectrum shows a blue continuum and weak, broad hydrogen Balmer lines having P-Cyg profiles, indicating that the object is a young Type IIP supernova. Weak He I 587.6 nm is also present. Cross-correlation with a library of supernova spectra using the "SuperNova Identification" code (SNID; Blondin & Tonry 2007, Ap.J. 666, 1024) yields a good match with several Type IIP supernovae a few days after explosion.
