8992017-04-16 16:42:50jlprietoJ. L. Prieto, J. KlusmeyerASAS-SNSN IaASAS-SNWe obtained a spectrum of ASASSN-17er 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 past peak with strong host galaxy contamination. Using SNID to fit the spectrum, the best fitting template is the normal SN Ia 2005hf at +9 days. After correcting the spectrum for the redshift of the host, we measure a Si II 6355 Angs. velocity of 8000 km/s.
