9002017-04-16 16:51:26jlprietoJ. L. Prieto, J. Klusmeyer, S. DongASAS-SNSN Ia1ASAS-SNWe 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.

JohnsonASAS-SNSN Ia1ASAS-SNWe obtained an spectrum of ASASSN-17ek on UT 2017 Apr. 2.99 with MagE mounted on the Magellan Baade 6.5m telescope at LCO. The spectrum is characteristic of a Type Ia around maximum light. Using SNID we the normal SN Ia 2006N at -1 days as the best fitting template.

8822017-03-30 20:31:20jlprietoJ. L. Prieto, E. FalcoASAS-SNSN Ia1ASAS-SNWe obtained a spectrum of ASASSN-17ee/AT2017ckx on UT 2017 March 29 with FAST mounted on the FLWO 1.5m telescope. The spectrum is that of a normal SN Ia around maximum light with strong host-galaxy contamination. Using SNID, the best-fit template is SN2003ic at -4 days with respect to B-band maximum light.
