T. Matheson, P. Challis, and R. Kirshner, Harvard-Smithsonian Center for Astrophysics, report that a spectrum (range 370–750 nm) of SN 2003ld (cf. IAUC 8260), obtained by M. Calkins on Jan. 13.16 UT with the Mt. Hopkins 1.5-m telescope (+ FAST), shows it to be a type-II supernova; adopting the NASA/IPAC Extragalactic Database (NED) recession velocity of 4213 km/s for the host galaxy, the expansion velocity derived from the minimum of the H_beta line is 6000 km/s. A spectrogram of SN 2003lo (cf. IAUC 8261), obtained on Jan. 13.18, shows it to be a type-IIn supernova; the spectrum shows a blue continuum with both broad and narrow hydrogen emission lines. A spectrogram of SN 2003lp (cf. IAUC 8261), obtained on Jan. 13.46, shows it to be a type-II supernova; adopting the NED recession velocity of 2702 km/s for the host galaxy, the expansion velocity derived from the minimum of the H_beta line is 8200 km/s. A spectrogram (range 370-750 nm) of SN 2003lq (cf. IAUC 8262), obtained on Jan. 13.15, shows it to be a type-Ia supernova about a week past maximum. Adopting the NED recession velocity of 7271 km/s for the host galaxy, the supernova expansion velocity is 9700 km/s for Si II (rest 635.5 nm). The spectral-feature age of the supernova is 6 ± 2 days after maximum light.
