A. V. Filippenko, R. T. Foley, and B. Swift, University of California, report that inspection of CCD spectra (range 320-1000 nm), obtained on Oct. 28 UT with the Shane 3-m telescope at Lick Observatory, reveals that SN 2003jd (IAUC 8232) is probably a peculiar type-Ic supernova, with some similarities to SNe 1998bw and 2002ap (Foley et al. 2003, PASP 115, 1220). The expansion velocity, measured from the bottom of the putative Ca II near-infrared triplet absorption line, is about 40000 km/s. The continuum is quite blue, perhaps more so than that of other 1998bw- like objects at a similar phase. It is possible that the object is a 1991T-like type-Ia supernova, although the peculiar type-Ic hypothesis is currently favored. A spectrum of SN 2003je (IAUC 8232) shows it to be of type II (perhaps type IIn), with low- contrast H_alpha emission superposed on a nearly featureless blue continuum. The corresponding absorption component of H_alpha is weak or absent. A noisy spectrum of SN 2003jf (IAUC 8233) suggests that it is a young type-II supernova with a featureless blue continuum.
