StanekASAS-SNSN Ia0.012ASAS-SNOptical spectra (range 350-760nm) of the supernova candidates ASASSN-16dm/2016blb (ATel #8882), ASASSN-16dn/2016blc (ATel #8885), and ASASSN-16dp/2016bli (ATel #8892), were obtained on UT 2016 April 2 with the F. L. Whipple Observatory 1.5-m telescope (+ FAST). Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) indicates the following matches. ASASSN-16dm is a Type II-P SN near peak (best match is SN 2006bp at +3 days), ASASSN-16dn is normal Type Ia SN before maximum light at z=0.012 +/- 0.003 (from SN lines, no host galaxy lines are detected; best match is SN 2007A at -3 days), and ASASSN-16dp is a Type Ia SN about a week after maximum (best match is SN 1999ef at +7 days). After correcting the spectra of ASASSN-16dn and ASASSN-16dp by the redshift of their host galaxies, we measure Si II 635.5nm expansion velocities of 10600 km/s and 11900 km/s, respectively. 2016TNSCR1008....1F
