R. J. Foley, D. S. Wong, M. Ganeshalingam, W. Li, and A. V. Filippenko, University of California, Berkeley, report that inspection of CCD spectra (range only 400-690 nm), obtained on May 27 UT with the Shane 3-m telescope at Lick Observatory, shows that SN 2004bw is of type I, possibly Ic, but the exact classification is uncertain due to the limited wavelength coverage. The spectrum resembles that of SN 2004aw as described by Matheson et al. (IAUC 8311).
