2003IAUC.8086....2P

M. Phillips and M. Hamuy, Carnegie Observatories, report that a spectrum (range 380-930 nm) of SN 2003bk, obtained on Mar. 3.28 UT with the Las Campanas Dupont 2.5-m telescope (+ WFCCD), shows it to be a highly reddened type-II supernova having a red continuum with a strong H_alpha line exhibiting a P-Cyg profile. The minimum of the H_alpha absorption yields an expansion velocity of 7600 km/s, assuming the NED recession velocity of 1252 km/s for the host galaxy. A spectrum of SN 2003bl, taken on Mar. 3.35, shows it to be a young type-II supernova with a blue continuum, weak P-Cyg Balmer lines, and He I at 587.6 nm; the minimum of the H_beta absorption yields an expansion velocty of 6300 km/s, assuming the NED recession velocity of 4295 km/s for the host galaxy. Hamuy adds that a spectrum of SN 2003bj (cf. IAUC 8085), obtained as above on Mar. 2.30 by M. Roth and N. Morrell, shows it to be a young type-II supernova having a blue continuum with weak H_alpha and H_beta P-Cyg lines and a well-defined He I 587.6-nm line.
