16312018-01-15 12:46:46jlprietoJ. L. Prieto (UDP)ASAS-SNSN Ia0.032ASAS-SNWe obtained an optical spectrum of SN2017hce on UT 2017 Oct. 25.1 with OSMOS mounted on the MDM 2.4m telescope at KPNO. The spectrum is that of a normal Type Ia after peak. SNID (Blondin & Tonry 2007) gives an average epoch of 13.5 days after peak and redshift from SN features of z=0.032 +/- 0.002.
