SN2003F  20021211.0   <190:C  KAI
SN2003F  20030108.16   167C   Puc
SN2003F  20030108.3    163:C  KAI
SN2003F  20030109.6    161C   BAO

# A host galaxy of SN 2003F (5:11:33.03, +17:03:28.4 (J2000.0), offset
# = 7"E, 6"N) is a disturbed spiral (Sdm:) galaxy UGC 3261.  It is
# near to the Galactic plain (b = -13o), so there are several
# foreground stars superimposed on the host galaxy.  A spectrum taken
# with the Las Campanas Observatory Baade 6.5-m telescope on Jan 9.11
# revealed that it is type Ia SN a few days before maximum.  Some
# reddening within the host galaxy is suggested, as well as Galactic
# one.  The reported magnitude is thus considerably brighter than
# expected maximum for typical SNe Ia (mag about 16.7) taking account
# of the redshift and the Galactic extinction.  Further magnitude
# estimates are urged.

SN2003G  20021212.0  <190:C  KAI
SN2003G  20030108.2   162:C  KAI
SN2003G  20030109.5   158C   BAO

# A host galaxy of SN 2003G (2:08:28.13, +6:23:51.9 (J2000.0), offset
# = 6"E, 10"N) is a face-on spiral (SAbc) galaxy IC 208.  A spectrum
# taken with Baade telescope on Jan 9.05 revealed that it is a young
# SN IIn.  The reported magnitudes are consistent with that of ordinal
# core-collapsed SNe.

SN2003H  20030103.0  <190:C  KAI
SN2003H  20030108.3   178:C  KAI
SN2003H  20030109.6   180C   BAO

# A host galaxy of SN 2003H (6:16:25.68, -21:22:23.8 (J2000.0)) is an
# interacting pair NGC 2207 (SAB(rc)bc pec) + IC 2163 (SB(rs)c pec).
# An offset from IC 2163 = eastern component of the pair is reported
# as 32"W, 10"N.  An offset from NGC 2207 is derived as 51"E, 2"S.  
# The classification was not been reported on IAUC 8045.  NGC 2207 had
# produced SN Ia 1975A (B=14.7 at maximum) and SN Ib(?) 1999ec
# (discovery mag about 17.9, past maximum).   

SN 2003E:
In [vsnet-campaign-sn 531] (Jan. 9):
>SN2003E  20021127.3 <185:C  KAI
>SN2003E  20030105.3  170:C  KAI
>SN2003E  20030107.3  170:C  KAI

># A host galaxy of SN 2003E (4:39:10.88, -24:10:36.5 (J2000.0), offset
># = 6"W, 9"N) is an edge-on spiral (Sbc) galaxy MCG -4-12-4, which
># makes a pair with MCG -4-12-3.  The SN is superimposed on the disk,
># so notable extinction is possible.  The expected maximum for typical
># unreddened (in the host galaxy) SN Ia is mag about 15.7.

A spectrum taken with Baade telescope on Jan 9.15 shows that it is a
young SN II.
