Abstract (from CDS):

R. J. Foley, R. Chornock, and A. V. Filippenko, University of California, Berkeley; and F. J. D. Serduke, Lawrence Livermore National Laboratory, report that inspection of CCD spectra (range 310-1000 nm), obtained on Sept. 3 UT with the Shane 3-m telescope at Lick Observatory, reveal that SN 2003he (IAUC 8182) is of type Ia, with a spectral-feature age of 9 ± 2 days past maximum brightness; the continuum is quite blue, contrary to the description given on IAUC 8189 (where galaxy contamination was not properly taken into account). SN 2003hs (IAUC 8191) is also of type Ia, but near maximum light. The spectrum exhibits relatively strong 580 nm Si II/Ti II absorption relative to the 615-nm Si II absorption, suggesting that SN 2003hs may be slightly subluminous.
