J. Sollerman, J. Andersson, M. Gustafsson, P. Jakobsson, and G. Oye, on behalf of the NORFA/NOT Summer School in Observational Astrophysics; and F. Patat, European Southern Observatory, report on spectroscopy obtained with the Nordic Optical Telescope (+ ALFOSC; range 350-950 nm, resolution 0.8 nm) on July 7.2 UT. A preliminary reduction of the spectrum of SN 2003gl (cf. IAUC 8163) shows it to be a type-Ia supernova, a few weeks after maximum light. SN 2003gk is probably of type Ib, though the low signal-to-noise ratio of the data makes the classification rather uncertain; the spectrum shows a reasonable resemblance to SN 1984L (Harkness et al. 1987, Ap.J. 317, 355), several weeks after maximum light, and the most prominent features are tentatively identified as He I, O I, and Ca II. The expansion velocity, deduced from the minimum of the He I 587.6-nm absorption trough, is 8300 km/s. This relatively low value, together with the absolute magnitude implied by the distance [43 Mpc; v(gal) = 3192 km/s, H_o = 72 km s**-1 Mpc**-1] and the observed magnitude at discovery (IAUC 8162), seem to confirm the spectral dating.
