We obtained SALT (+RSS) spectroscopy of PS16eot (= SN 2016hfb) on 2016 Oct 19.9 UT, covering the wavelength range 340-920 nm. Narrow emission lines confirm the redshift of the host galaxy UGC 2372 at z = 0.026 (Haynes et al. 1997, AJ, 113, 1197; via NED).

Cross-correlation of the spectrum with a supernova template library using SNID (Blondin & Tonry 2007, ApJ, 666, 1024) shows PS16eot is a type-II supernova approximately one week past maximum light. A good SNID match is obtained with the type-IIP SN 2004et at +6 days. The expansion velocity for PS16eot, measured to the trough of the H-beta line, is approximately 8000 km/s.

Our spectrum is posted on the Transient Name Server SN 2016hfb page.

PS16eot was discovered as part of the Pan-STARRS Survey for Transients (Huber et al. 2015, ATel #7153). Information on all PSST objects is available at http://star.pst.qub.ac.uk/ps1threepi/
