A spectrum was obtained on UT May 09.36 of AT2016ccm in IC 983 using the 1.82-m Plaskett telescope (National Research Council of Canada) covering the range 365-710 nm (resolution 0.35 nm). Cross-correlation with a template library using SNID (Blondin & Tonry 2007, ApJ, 666, 1024) shows AT2016ccm to be a core-collapse supernova approximately 1 week post maximum light. We find a fit to the template of (SN IIp) 2006bp at 7 days past maximum. Our solution yields a host redshift of z=0.017. The apparent host is IC983 with a published redshift (NED) of z=0.018.
