R. Chornock, S. Jha, and A. V. Filippenko, University of California at Berkeley, report that inspection of CCD spectra (range 320-1000 nm), obtained at the Shane 3-m telescope at Lick Observatory on Sept. 2.2 UT, reveals that SN 2003hq (IAUC 8191) is a type-Ia supernova with a spectral-feature age of 4 (± 2) days before maximum light. The minimum of the strong Si II 635.5-nm absorption feature is observed at 640 nm, implying a host recession velocity of approximately 12000 km/s (assuming a normal supernova expansion velocity of 10000 km/s).
