Abstract (from CDS):

A. V. Filippenko and R. J. Foley, University of California, Berkeley; and F. J. D. Serduke, Lawrence Livermore National Laboratory, report that inspection of CCD spectra (range 320-1000 nm), obtained on Aug. 28 UT with the Shane 3-m telescope at Lick Observatory, reveals that SN 2003hj (IAUC 8184) is of type Ia, about 2 weeks past maximum brightness, at redshift 0.076 (determined from narrow H_alpha emission in the host galaxy nucleus). Supernovae 2003hi (IAUC 8184), 2003hl (IAUC 8184), 2003hk (IAUC 8184), 2003gv (IAUC 8175), and 2003hc (IAUC 8179) are all relatively normal type-II supernovae, with hydrogen Balmer lines having P-Cyg profiles. SN 2003gw (IAUC 8176) is also probably of type II, but the noisy spectrum exhibits only rather narrow (FWHM = 2000 km/s) H_alpha emission. SN 2003hm (IAUC 8185) is of type Ia, about 2 months past maximum brightness. Supernovae 2003he (IAUC 8182) and 2003hp (IAUC 8188) show some broad undulations and are probably supernovae at respective redshifts of 0.025 and 0.051 (determined from narrow H_alpha emission in the host galaxy nuclei), though of uncertain types because their spectra are noisy; the former has a very red continuum, while the latter is reasonably blue. SN 2003hf (IAUC 8182) might be of type II, exhibiting a featureless blue continuum, but such characteristics are rare for a type-II supernova as old as SN 2003hf (at least 2 weeks past the explosion).
