A spectrum was obtained on UT April 30.39 of MASTER OT J140958.91+174549.4 (CSS160427:140959+174549) 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 MASTER OT J140958.91+174549.4 to be a core-collapse supernova near maximum light. We find a fit to the template of (SN IIp) 2006bp at maximum. Our solution yields a host redshift of z=0.019. The apparent host is IC983 with a published redshift (NED) of z=0.018.
