1641 2018-01-16 02:08:56 Matthew Siebert G. Dimitriadis, M. R. Siebert, R. J. Foley (UCSC) None SN Ia 0.018 1 Similar to SN 1986G and other "transitional" SNe Ia. We measure an Si II 6355 velocity of -11,500 km/s. 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). 2018TNSCR..74....1D
