SUPERNOVA 2010lv
     G. Folatelli, University of Tokyo; G. Pignata, Universidad Andres Bello;
and J. Anderson and F. Forster, Universidad de Chile, on behalf of the
Millennium Center for Supernova Science, report that they have obtained a
spectrum (range 450-800 nm) of 2010lv (cf. CBET 2622) on Feb. 28.16 UT with
the SOAR telescope (+ Goodman HTS).  The spectrum indicates that 2010lv is a
type-Ia supernova between one and two months after maximum light; comparison
with template spectra using the "Supernova Identification" code (SNID; Blondin
and Tonry 2007, Ap.J. 666, 1024) provides good matches to those of SNe 1986G,
1989B, 2004S, and 1994D at ages between +32 and +50 days.  Given that the
discovery of this supernova occurred on 2010 Dec. 31, the actual age should
be greater than +45 days.  Additionally, SNID provides an estimated redshift
of 0.07 for SN 2010lv.
