We obtained an optical spectrum (range 397-686nm) of ASASSN-16ej/AT2016bmc (ATel #8939) on UT 2016 Apr. 15.4 with OSMOS mounted on the MDM 2.4-m telescope. The spectrum of ASASSN-16ej/AT2016bmc is that of a normal Type Ia SN before maximum light. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin & Tonry 2007, ApJ, 666, 1024) shows that the best match is SN2013ic at -4 days. After correcting the spectrum for the redshift of the host galaxy, we measure a Si II 635.5nm expansion velocity of 10400 km/s. The spectrum can be found at the TNS.
