We report that a CCD spectrum (range 350-1050 nm) of SN2016igr was obtained on Dec 1, 5.95 UT, with the 3-m Shane reflector (+Kast) at Lick Observatory. We classified the event via cross-correlation with a library of supernova spectra using the "SuperNova IDentification" code (SNID; Blondin & Tonry 2007, Ap.J. 666, 1024). The spectrum shows SN2016igr to be a normal Type Ia supernova within a few days of peak brightness. SNID identifies spectroscopic similarities to SN1981B and SN1994ae.
