36542019-03-16 22:50:51UCSCTr_Bot1G. Dimitriadis, R. J. Foley (UCSC)SN Ia0.042SN Ia at -2 days. Good fits with SN 1991T-like and SN 1999aa-like spectra a few days before maximum. We measure an Si II 6355 velocity of -10,800 km/s. Our classification agrees with the FTN / FLOYDS-N spectrum from the Global SN Project. ATel: 12585

Andrew Howell, Curtis McCully, Stefano ValentiGlobal SN ProjectSN Ia0.041856Global SN ProjectUsing Superfit (Howell et al. 2005, ApJ, 634, 1190) and SNID (Blondin & Tonry 2007, ApJ, 666, 1024), we find good fits to several Type Ia SNe around maximum light at the redshift of the proposed host galaxy (z=0.041856; 1995ApJS..100...69F, via NED). At the redshift, the extinction-corrected absolute magnitude in B-band taken at UTC 2019-03-16 08:20:40 is -19.4, which is consistent with the Ia classification and its phase. We measure a Si II 6355 velocity of -11,000 km/s.
