Abstract (from CDS):

A. V. Filippenko and R. Chornock, University of California, Berkeley, report that inspection of CCD spectra (range 320-920 nm), obtained on Sept. 28 UT with the Keck-I 10-m telescope, reveals that SN 2003hf (IAUC 8182) is indeed of type II, as suggested on IAUC 8189; very strong, broad H_alpha emission is present, with essentially no absorption, but other features have P-Cyg profiles. Based on the available spectra, which closely resemble those of SN 1979C (Branch et al. 1981, Ap.J. 244, 780), it is likely that analysis of the light curve will show that the object is specifically of type II-L. SN 2003hp (IAUC 8188, 8189) is a 1998bw-like type-Ic supernova (see Foley et al. 2003, PASP 115, 1220, and references therein), roughly 1 month past maximum brightness. SN 2003ht (IAUC 8192) is of type II, in the nebular phase. SN 2003hw (IAUC 8198) is of type Ia, about 2 months past maximum brightness. SN 2003ig (IAUC 8207) is of type Ic, within a week past maximum brightness. SN 2003gq (IAUC 8168), whose early- time spectrum (IAUC 8170) resembled that of SN 1991T but with low ejection velocities, continues to exhibit a spectrum very similar to that of SN 2002cx (Li et al. 2003, PASP 115, 453), characterized by unusually narrow lines.
