SN2003bk 20030131.5 <185:C KAI SN2003bk 20030228.5 170:C KAI SN2003bk 20030302.3 170:C KAI # SN 2003bk (12:22:42.14, +9:20:01.2 (J2000.0), offset = 2"W, 4"N) is # hosted by NGC 4316, a nearby edge-on spiral (Sbc) galaxy. It is a # probably member of the Virgo cluster. The Las Campanas spectrum # taken on Mar. 3.28 shows that it is highly reddened type II SN. SN2003bl 20020613.3 <190:C KAI SN2003bl 20030302.5 184:C KAI SN2003bl 20030303.5 184:C KAI # SN 2003bl (13:57:30.65. +6:05:36.4 (J2000.0), offset = 15"E, 13"S) # is hosted by NGC 5374, a barred spiral (SB(r)bc?) galaxy. There is a # bright (mag about 11) about 1'.3 due west of NGC 5374. The Las # Campanas spectrum taken on Mar. 3.35 revealed that it is young SN # II with a blue continuum (reddening is negligible). It shows a weak # H_alpha line and a He I 587-nm line, which suggest that it is # possibly a type-IIb event. The discovery magnitude is consistent # with one for the normal gravitational collapse event.

The ># expected maximum for typical SN Ia is about the discovery magnitude. The Las Campanas spectrum (Mar. 2.30) shows that it is young type II SN. Also this SN shows a weak H_alpha line and well-defined He I 587-nm line, which suggest that it is possibly a type-IIb event. And it is very luminous as a core-collapse event.
