We report that a CCD spectrum (range 350-1050 nm) of PSN J15502534+1856075 was obtained on Feb. 07.6 UT with the Kast spectrograph on the 3-m Shane telescope at Lick Observatory. The spectrum shows that the object, located in NGC 6004, is a Type II supernova about one to two months after explosion; strong hydrogen Balmer lines and other normal Type-II features with well-developed P-Cygni profiles are visible on a continuum. The object was classified through cross-correlation with a collection of supernova spectra using the "SuperNova Identification code" (SNID; Blondin & Tonry 2007, Ap.J., 666, 1024), which indicates good matches with several Type IIP supernovae from a few weeks to a few months past explosion.
