Abstract (from CDS):

S. Blondin, M. Modjaz, R. Kirshner, and P. Challis, Harvard-Smithsonian Center for Astrophysics, report that a spectrum (range 350-740 nm) of 2006gr (cf. CBET 641), obtained on Sept. 25.37 UT by P. Berlind with the F. L. Whipple Observatory 1.5-m telescope (+ FAST), shows it to be a type-Ia supernova around maximum light, confirming the identification of Quimby et al. (cf. CBET 641). However, the Si II absorption at 580 nm is stronger than in "normal" type-Ia supernovae, and absorption due to Ti II is present near 420 nm, as in the subluminous supernova 1991bg (see a comparison plot at http://www.cfa.harvard.edu/oir/Research/supernova/spectra/sn2006gt_comp.gif). Adopting the NED recession velocity of 13422 km/s (from Smith et al. 2004, A.J. 128, 1558) for the host galaxy (whose 2MASX position is given as R.A. = 0h56m18.1s, Decl. = -1d37m33s, equinox 2000.0), the maximum absorption in the Si II (rest 635.5 nm) line is blueshifted by roughly 10500 km/s.
