8252017-03-03 13:01:52jlprietoJ. L. Prieto, E. FalcoASAS-SNSN Ia1ASAS-SNWe obtained an optical spectrum of ASASSN-17df/AT2017bos on UT 2017 Mar 2.2 with FAST mounted on the FLWO 1.5m telescope. The spectrum shows features consistent with a Type Ia SN around maximum light on top of strong host galaxy contamination. We measure Si II 6355 Angs. expansion velocity of 9800 km/s from the minimum of the P-Cygni absorption trough.

We detect a subtle absorption feature at ~6350 A, which may be caused by C II 6580 at -10,600 km/s. The cool photosphere and possible carbon detection are both notable features of the peculiar SN 2006bt (Foley et al., 2010, ApJ, 708, 1748).
