We obtained SALT (+RSS) spectroscopy of SN 2016iae (= ATLAS16dvr; Tonry et al. 2016, ATel #9749) on 2016 Nov 12.9 UT covering the wavelength range 350-940 nm. The spectrum shows a relatively blue continuum, with well-developed broad absorption features, including strong Si II (rest 635.5 nm). Cross-correlation of the supernova spectrum with a template library using SNID (Blondin & Tonry 2007, ApJ, 666, 1024) shows SN 2016iae is a type-Ic supernova approaching maximum light. Good SNID matches are obtained with the type-Ic SN 2007cl at -6 days and SN 2004aw at -2 days.

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