Dave Balam report/s a classification of object: SN 2016bkr

Type: SN Ia-pec
Redshift: 0.032

Remarks: A spectrum was obtained of SN 2016bkr (ATEL #8857) on Apr. 8.41 UT using the 1.82-m Plaskett telescope (National Research Council of Canada) covering the range 385-710 nm (resolution 0.32 nm). Cross-correlation with a template library using SNID (Blondin & Tonry 2007, ApJ, 666, 1024) shows 2016bkr to be a peculiar type-Ia supernova approximately 12 days post-maximum light. There was strong H-alpha emission from the presumed host galaxy (2MASS J11032043+7153141) that yielded a host galaxy redshift of z=0.032. We find a good fit of the supernova spectrum to that of SN 1997br at 12 days post-maximum light. Using the presumed redshift of z=0.032 we measure an expansion velocity for the Si II (rest 635.5 nm) feature of 13,200 km/s

The following Classification spectrum was provided:
