2004IAUC.8353....3F

R. J. Foley, D. S. Wong, M. Moore, and A. V. Filippenko, University of California, Berkeley, report that inspection of CCD spectra (range 330-1000 nm), obtained on June 13 UT with the Shane 3-m telescope at Lick Observatory, shows that SN 2004bu (IAUC 8343) is similar to the peculiar type-Ic supernovae 1998bw and 2002ap (Foley et al. 2003, PASP 115, 1220), as previously suspected by Foley et al. (cf. IAUC 8345). SN 2004bw (IAUC 8345) is of type Ia, with a spectral-feature age of 7 ± 2 days after maximum brightness. SN 2004bz (IAUC 8350) and SN 2004cb in ESO 445-G20 (IAUC 8350) are also of type Ia, roughly 3 weeks past maximum brightness. The highly reddened SN 2004cc is of type Ic, probably about one week before maximum brightness.
