900 2017-04-16 16:51:26 Jose Prieto J. L. Prieto, J. Klusmeyer, S. Dong ASAS-SN SN Ia 1 ASAS-SN We obtained a spectrum of ASASSN-17ez on UT 2017 Apr. 16.2 with OSMOS mounted on the MDM 2.4m telescope at KPNO. The spectrum is characteristic of a normal SN Ia around peak. Using SNID to fit the spectrum, the best fitting template is the normal SN Ia 2006cf at +2 days. After correcting the spectrum for the redshift of the host, we measure a Si II 6355 Angs. velocity of 11600 km/s. 2017TNSCR.443....1P
