Abstract (from CDS):

T. Matheson, P. Challis, and R. Kirshner, Harvard-Smithsonian Center for Astrophysics, report that a spectrum (range 370-750 nm) of SN 2002hu (cf. IAUC 8012), obtained by L. Macri on Nov. 8.80 UT with the Mt. Hopkins 1.5-m telescope (+ FAST), shows it to be a type-Ia supernova before maximum. Narrow H-alpha emission from a nearby H II region indicates a recession velocity of about 11000 km/s for the host galaxy. The expansion velocity derived from the minimum of the Si II line (rest 635.5 nm) is about 10500 km/s. The spectral-feature age of the supernova is 5 ± 2 days before maximum light. A spectrum of SN 2002hv (cf. IAUC 8012), obtained by P. Berlind on Nov. 9.49 with the same telescope, shows it to be a type-Ia supernova a few weeks past maximum.
