6262016-12-06 13:43:40jlprietoS. Frank (OSU), J. L. Prieto (UDP/MAS), K. Z. Stanek (OSU)ASAS-SNSN IaASAS-SNWe report optical spectroscopic observations of ASASSN-16bx/2016ajk (ATel #8712) and ASASSN-16cy/2016ayf (ATel #8801) obtained by S. Frank on UT 2016 March 14-15 with OSMOS (range 398-686 nm) mounted on the MDM 2.4m telescope at KPNO. We used SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) to aid with the type and phase of the SN spectra. ASASSN-16bx is a Type Ia SN about one month after peak brightness (best fit SNID template is SN1999gd at +34 days) and ASASSN-16cy is a normal Type Ia a couple days before maximum (best fit SNID template is SN2002de at -4 days). After correcting the spectrum of ASASSN-16cy for its host galaxy redshift (z=0.034811), we measure a expansion velocity from the Si II 635.5nm line of 12600 km/s.
