SUPERNOVAE 2008ah
     M. Stritzinger, G. Folatelli, and N. Morrell, on the behalf of the
Millennium Center for Supernova Studies and the Carnegie Supernova Project,
report that they have obtained a spectrum (range 400-940 nm) of 2008ah (cf.
CBET 1255) with the European Southern Observatory's New Technology Telescope
(+ EMMI) on Feb. 14.2 UT, showing 2008ah to be a type-Ia supernova a few
days past maximum light.  With aid from the "Supernova Identification" code
(SNID; Blondin and Tonry 2007, Ap.J. 666, 1024), 2008ah is found to be most
similar to supernova 1989B at four days past maximum light.  Adopting a
host-galaxy recession velocity of 20519 km/s (SDSS data release 2; Abazajian
et al. 2004, A.J. 128, 302) for the host galaxy, an expansion velocity of
10800 km/s is measured from the Si II 615-nm line.
