SUPERNOVA 2012ah IN NGC 7637
     T. de Jaeger, S. Gonzalez and J. Anderson, Universidad de Chile; and G.
Pignata, Universidad de Andres Bello, on behalf of the Millennium Center for
Supernova Science, report on optical spectroscopy (range 380-900 nm) of PSN
J23255963-8154333 = 2012ah (cf. CBET 3028) that was obtained on Feb. 22.2 UT
with the Magellan II Clay 6.5-m telescope (+ LDSS3) at Las Campanas
Observatory.  Cross-correlation with a library of supernova spectra using the
"Supernova Identification" code (Blondin and Tonry 2007, Ap.J. 666, 1024)
gives best matches with type-Ia supernovae a few days past maximum light.
Using the host-galaxy recession velocity from NED (Koribalski et al. 2004,
A.J. 128, 15) of 3718 km/s, the velocity of the Si II 635.5-nm feature is
estimated to be approximately 11000 km/s.
