Pittsburgh), Yago Ascasibar (UAM), Kristin Fiegert (AAO)NoneSN Ia0.084Classification was done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024), and the spectrum is available at the IAU Transient Name Server (see https://wis-tns.weizmann.ac.il/). The spectrum shows the Si II 6355A absorption, and MgII, and FeII absorption features characteristic of type Ia supernovae (SNe Ia). SNID gives a reasonable fit to all its main spectral features with spectra of normal and 91T-like SNe Ia a few days before peak brightness placed at redshift ~0.08, consistently with that of the host galaxy (0.084). We measure a Si II 6355 velocity of -9,500 km/s.
