SUPERNOVA 2008bu IN ESO 586-G2
     R. Covarrubias, Observatories of the Carnegie Institution of Washington
and Anglo-Australian Observatory; and N. Morrell, on behalf of the Carnegie
Supernova Project, report a spectroscopic observation (range 400-1000 nm)
obtained on Apr. 22.24 UT with the Magellan II Clay telescope (+ LDSS3) at
Las Campanas Observatory, which shows 2008bu (cf. CBET 1341) to be a young
type-II supernova.  Comparison with a library of supernova spectra via the
'superfit' tool (Howell et al. 2005, Ap.J. 634, 1190) gives a very good
match with the spectrum of SN 1993W at four days after explosion.  Assuming
for the host galaxy (ESO 586-G2) the NED recession velocity of 6630 km/s
(Theureau et al. 1998, A.Ap. Suppl. 130, 333) an expansion velocity of 9200
km/s is derived for the minimum of the H_beta absorption.
