A spectrum was obtained on UT June 10.39 of (PSST) 15apv (ATEL 7598) using the 1.82-m Plaskett telescope (National Research Council of Canada) covering the range 365-720 nm (resolution 0.35 nm). Cross-correlation with a template library using SNID (Blondin & Tonry 2007, ApJ, 666, 1024) shows 15apv to be a core-collapse supernova about 1 week post maximum. We find a fit to the template of (SN IIp) 1999em at T = +7 days. There are several candidates as the host galaxy within 15 seconds of arc: SDSS J210817.71+170957.9 (g=21.09, r=20.24) and SDSS J210817.88+171008.4 (g=20.96, r=20.19). Our fit to the supernova spectrum suggests a redshift of z = 0.024.
