SUPERNOVAE 2009lg, 2009lh, 2009lk, 2009lm, 2009ln, AND 2009lo
     P. Challis, Harvard-Smithsonian Center for Astrophysics (CfA), on behalf
of the CfA Supernova Group, reports the following spectroscopic observations
obtained on Nov. 23 at the MMT telescope (+ Blue Channel spectrograph; range
320-850 nm).  Cross-correlation with a library of supernova spectra using the
"Supernova Identification" code (SNID; Blondin and Tonry 2007, Ap.J. 666,
1024) indicates that 2009lg (cf. CBET 2023) best matches the normal type-Ia
supernova 2003du at ten days after maximum with a redshift of 0.058; 2009lh
(cf. CBET 2024) best matches the type-Ia supernova 1989B at 13 days after
maximum light with a redshift of 0.07; 2009lk (cf. CBET 2028) best matches
the type-IIP supernova 2004et at a phase of 25 days after maximum light with
a redshift of 0.041; 2009lm (cf. CBET 2032) best matches the type-IIP
supernova 2004dj at maximum light with a redshift of 0.018; 2009ln (cf. CBET
2035) best matches the type-IIP supernova 2004et at 12 days after maximum
light with a redshift of 0.035; and 2009lo (cf. CBET 2036) best matches the
type-IIP supernova 2005cs at two days after maximum light with a redshift of
0.03.
