J. L. Prieto, Princeton University, reports that he obtained an spectrum (range 370-930 nm) of PSN J13545169-2630464 = SN 2012bk on Mar. 27.22 UT using the du Pont 2.5-m telescope (+ WFCCD) at Las Campanas Observatory. The spectrum shows a blue continuum with several broad absorption features, the strongest ones at 578, 633, and 657 nm. The redshift of the host galaxy is determined from unresolved emission lines in the spectrum that are consistent with the wavelengths of H-beta, [O III] 500.7-nm, and H-alpha at z = 0.0176. After correcting the spectrum of the object to the rest wavelength, we find that the absorption features are consistent with blueshifted He I lines, most prominently the He I 587.5-nm has the absorption minimum at -10300 km/s. These properties are consistent with a type-Ib supernova around maximum light (e.g., Modjaz et al. 2009, Ap.J. 702, 226).
