# 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:

># 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

  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):

># 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:

># 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:
