We report an optical spectrum (range 340-890 nm) of PS15abr(see ATel #7390) that was obtained on May 21.7 2015 UT with the 2.4-m telescope (+YFOSC) at LiJiang Gaomeigu Station of YNAO. The spectrum is consistent with a type II-P supernova at about 1 month after 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 2006bp at t = +34 days. Adopting a redshift of 0.025 its host galaxy SDSS J120235.31+202439.6, an expansion velocity of about 8200 km/s can be derived from the absorption minimum of Ha.
