We report the classification of PS16ccj from spectroscopic observation with KOSMOS on the Mayall telescope. The observation was made on 2016 May 05 UT. We classify PS16ccj as a SN Ia near maximum light. A redshift of 0.056 is determined from host-galaxy emission lines. Cross-correlation with a library of SN template spectra using SNID (Blondin & Tonry 2007, ApJ, 666, 1024) finds a best-fit phase of -1 (+/-3) days relative to maximum light. We measure a Si II 6355 velocity of -10,700 km/s.
