SUPERNOVA 2008do IN UGC 8179
     S. Blondin, Harvard-Smithsonian Center for Astrophysics (CfA), on
behalf of the CfA Supernova Group, reports that a spectrum (range 400-1000
nm) of 2008do (cf. CBET 1413), obtained on June 24 UT by G. Armstrong
(University of Sydney) and P. Challis (CfA) with the Magellan Clay 6.5-m
telescope (+ LDSS3), shows it to be a young type-II supernova.  The
spectrum consists of a blue continuum with shallow P-Cyg profiles of the
Balmer series and He I (587.6 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 2008do is most similar to
the type-II-plateau supernova 2004et at two weeks past explosion.  Adopting
a recession velocity of 15548 km/s for the host galaxy (from The Updated
Zwicky Catalog, http://tdc-www.harvard.edu/uzc/), the maximum absorption in
the H_beta line (rest 486.1 nm) is blueshifted by roughly 11000 km/s.
