We report that a CCD spectrum (range 350-1050 nm) of PSN J09254453+3416361 (ATel 8077) was obtained on Sep. 14.4 UT with the Kast spectrograph on the 3-m Shane telescope at Lick Observatory. The spectrum shows that the object is a Type II supernova, probably several weeks after explosion; strong hydrogen Balmer lines (as well as other features) with well-developed P-Cygni profiles are visible. Object classification was performed using Superfit (Howell et al. 2005, ApJ, 634, 1190). This SN II has a large offset (43".0 W, 2".0 S) from the nucleus of its low-redshift (z = 0.0054; SDSS Data Release 4, 2005) host galaxy UGC 5015, making it ideal for late-time studies; follow-up observations are encouraged.
