2011CBET.2621....1M

G. H. Marion and P. Challis, Harvard-Smithsonian Center for Astrophysics (CfA), on behalf of the CfA Supernova Group, report that a spectrum (range 340-740 nm) was obtained of 2010lt (cf. CBET 2618) on Jan. 3 UT by P. Berlind with the F. L. Whipple Observatory 1.5-m telescope (+ FAST). Cross- correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666, 1024) shows that the object is a sub-luminous (1991bg-like) type-Ia supernovae near maximum light.
