D. Milisavljevic, M. R. Drout, and G. H. Marion, Harvard-Smithsonian Center for Astrophysics, report that an optical spectrum (range 410-935 nm; resolution 0.4 nm) of PSN J05224150-3903443 = SN 2012gk, obtained on Nov. 17.3 UT with the 6.5-m Magellan Baade telescope (+ IMACS), shows it to be a type-II supernova. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) shows matches with normal type-IIP events approximately three weeks after maximum light. The best match is with SN 2004et at 23 days post-maximum. After correcting for the host galaxy (ESO 305-21) redshift of z = 0.050415 (de Souza et al. 1997, A.Ap. Suppl. 125, 329; via NED), the velocity of the minimum of the H_alpha feature is estimated to be approximately 10500 km/s.
