We report the spectroscopic classification of PSN J01462790-5840238 using a near-infrared spectrum (range 800-2400 nm) obtained on November 30.1 UT with the FoldedPort Infrared Echellette (FIRE) spectrograph on the 6.5-m Magellan Baade Telescope at Las Campanas Observatory. The near-infrared spectrum is similar to that of SN 2010ae near maximum light (Stritzinger et al. 2013). The spectrum separately resolves the 3 components of the Ca II IR-triplet (854.2, 866.2, 849.8 nm) and the velocity for Ca II is approximately 5000 km/s, measured at the absorption minima and using a redshift z=0.007385 for the presumed host ESO 114- G 007 (Koribalski et al. 2004 AJ, 128, 16, via NED).
We also obtained uBVgri images with the Swope 1-m on Nov 29.0 UT. The un-subtracted V magnitude is 14.2. Adopting the distance modulus of the presumed host (32.1, via NED), the absolute V magnitude is approximately -15.0.
