SUPERNOVAE 2008du AND 2008dw
     T. N. Steele, R. Mostardi, C. V. Griffith, and A. V. Filippenko,
University of California, Berkeley, report that inspection of CCD spectra
(range 330-1000 nm), obtained on July 4 UT with the 3-m Shane reflector (+
Kast) at Lick Observatory, shows that 2008du (CBET 1423) is a type-Ic
supernova, near maximum brightness.  SN 2008dw (CBET 1426) is a type-II
supernova, also near maximum brightness.  The emission component of H-alpha
greatly dominates over the absorption component, though the other members of
the hydrogen Balmer series have more typical P-Cyg profiles.
