# SN 2003gu (23:02:59.45, +34:43:19.6 (J2000.0), offset = 1"E, 18"S)
# is hosted by UGC 12331, a dim spiral (S?) galaxy.  There is a
# foreground star (red mag about 17) at about 19"E and 5"S of the
# nucleus of UGC 12331.  The expected maximum for typical SN Ia is mag
# about 16.3.

  A spectrum taken with Baade telescope on Jul. 31.44 revealed that it
is really a type Ia SN, about a month after maximum light.  The latter
source I quoted was possibly a foreground red star, because it is
clearly detected on 2MASS public images. 

SN 2003gi:

>SN2003gi  20030429.134 <180:C  MLF

>SN2003gi  20030601.103  162:C  MLF
># SN 2003gi (0:38:32.67, -24:20:33.5 (J2000.0), offset = 1"E, 9"S) is
># hosted by IC 1561, a barred-spiral (SBb) galaxy which is a member of
># a IC 1562 group = KTS 05.  The expected maximum for typical SN Ia is
># mag about 15.3.  

  A spectrum taken with Baade telescope on Jul. 31.32 revealed that it
is also a type Ia SN, around 2.5 months after maximum.

SN 2003gr:
In [vsnet-campaign-sn 661] (Jul. 28):
>SN2003gr  20021029.2 <190:C  KAI
>SN2003gr  20030727.5  163:C  KAI
>SN2003gr  20030728.5  164:C  KAI
># SN 2003gr (23:38:12.67, -20:46:56.0 (J2000.0), offset = 6"W, 1"N) is
># hosted by MCG -04-55-14, a barred-spiral (SB(s)a) galaxy.  The
># expected maximum for typical SN Ia is consistent with the discovery
># magnitude. 

  The Baade spectrum taken on July 31.31 revealed that it is truely SN
Ia about 10 days after maximum.

># SN 2003gs seems to be a subluminous SN Ia near maximum on July 30.4
># UT.  Further magnitude estimates are quite encouraged.

# The colour of SN 2003gs also support that it would be a subluminous
# SN Ia.  The extinction seems to be negligible.
