254 2016-06-09 20:11:29 Isaac Shivvers Heechan Yuk, Isaac Shivvers, Benjamin Stahl, Alexei Filippenko LOSS SN Ia 0.0604 1 LOSS We report that a CCD spectrum (range 350-1050 nm) of AT2016cpw was obtained on Jun. 08.5 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) including the updated templates of Silverman et al. 2012, MNRAS, 425, 1789 and Liu & Modjaz, 2014, arXiv:1405.1437. The spectrum shows that AT2016cpw is a normal Type Ia supernova about one week after peak brightness. SNID identifies spectroscopic similarities to SNe 1994ae, 1995D, and 2007kk, and after correcting for the host galaxy's redshift of z = 0.060362 (2MASX J21412438-1404429; NED) the Si II 635.5 nm absorption minimum indicates an expansion velocity of 12,500 km/s.
