We report on the spectroscopic classification of PSN J01440799-6107074 using a near-infrared spectrogram (range 800-2500 nm) obtained on Mar. 8.02 UT with the FoldedPort Infrared Echellette (FIRE) spectrograph on the 6.5-m Magellan Baade Telescope at Las Campanas Observatory. The near-infrared spectrum shows that it is a type-Ia supernova. The spectrum resembles the near-infrared spectrum of SN 2011fe at maximum light (Hsiao et al. 2013, Ap.J. 766, 72). The supernova redshift approximately matches the redshift of the presumed host galaxy (ESO 114- G 004) at z = 0.021275 (Muriel et al. 1995, A.J. 110, 1032, via NED).

Two optical photometric observations taken with the 1-m Swope Telescope on Mar. 7.01 and Mar. 8.00 UT show the supernova declined slightly from V=15.63 to V=15.64, consistent with a type-Ia supernova near maximum light.
