# SN 2003dc (13:54:21.70, +05:46:09.3 (J2000.0), offset = 1"E, 2"S) is
# hosted by a very dim (R ~ 20) galaxy, which appears almost as a
# point source on DSS image.

SN 2003cr:
In [vsnet-campaign-sn 593] (Apr. 01):

>SN2003cr  20030331.18  177:C  Bol
>SN2003cr  20030331.894 175:C  Bol
># SN 2003cr (14:58:35.53, +44:53:06.4 (J2000.0), offset = 5"W, 5"N) is
># hosted by UGC 9639, a spiral (Sab) galaxy.  The expected maximum for
># typical SN Ia is consistent with the discovery magnitude.  There is
># a foreground star (mag about 17) at NE of the nucleus of the host
># galaxy. 

  The UCB team took spectra of SNe on Apr. 8, which shows that SN
2003cr is probably SN Ic within a few weeks past maximum.  

SN 2003da: 
In [vsnet-campaign-sn 598] (Apr. 8):
>SN2003da  20030202.0  <190C  Bol
>SN2003da  20030302.0  <190:C Bol
>SN2003da  20030406.9   159C  Bol
>SN2003da  20030407.83  159C  Bol
># SN 2003da (9:23:47.56, +42:10:48.6 (J2000.0), offset = 2"W, 12"S) is
># hosted by UGC 4992, an edge-on spiral (sc) galaxy.  There is a
># foreground star or companion compact galaxy (mag about 16) about 17"
># due east of the nucleus of UGC 4992.  The expected maximum for
># typical SN Ia is mag about 15.4. 

  The UCB team also revealed that it is type II SN soon after
explosion (Apr. 8)

SN 2003db:
In [vsnet-campaign-sn 598] (Apr. 8)
>SN2003db  20030222.0  <190C  Bol
>SN2003db  20030407.0   175C  Bol

># SN 2003db (9:36:58.83, +31:20:01.7 (J2000.0), offset = 9"E, 9"N) is
># hosted by MCG +05-23-21, a small spiral (S?) galaxy.  The expected
># maximum for typical SN Ia is mag about 16.9.

  It is also type II, a few weeks after explosion.

  The independent discovery by LOTOSS is also reported:
