SUPERNOVA 2007od IN UGC 12846
     S. Blondin, Harvard-Smithsonian Center for Astrophysics (CfA), on
behalf of the CfA Supernova Group, reports that a spectrogram (range
350-740 nm) of 2007od (cf. CBET 1116), obtained by M. Calkins on Nov. 4.11 UT
with the F. L. Whipple Observatory 1.5-m telescope (+ FAST), shows it to be a
type-II supernova around 2 weeks past explosion.  The spectrum consists of a
blue continuum and P-Cyg lines of the Balmer series, consistent with the
plateau phase of a normal type-II supernova.  Cross-correlation with a
library of supernova spectra using the "Supernova Identification" code (SNID;
Blondin and Tonry 2007, Ap.J. 666, 1024) indicates that 2007od is most
similar to the type-II supernova 1999em at 10 days past explosion.  Adopting
a recession velocity of 1739 km/s for the host galaxy (from de Vaucouleurs et
al. 1991, Third Ref. Cat. of Bright Galaxies), the maximum absorption in the
H_beta line (rest 486.1 nm) is blueshifted by roughly 8600 km/s.
