# A host galaxy of SN 2003aa (10:46:36.82, +13:45:32.2 (J2000.0),
# offset = 26"E, 30"N) is a face-on barred-spiral (SB(rs)c;LINER Sy)
# galaxy NGC 3367.  This galaxy has also produced SN Ia 1986A (maximum
# mag 14.4) and SN II-p 1992C (discovered at mag 16.5 after maximum).

SN 2003Y:
In [vsnet-campaign-sn 550] (Jan. 31):
>SN2003Y  20021225.3  <190:C  KAI
>SN2003Y  20030129.3   174C   KAI

># A host galaxy of SN 2003Y (8:54:34.60, +57:10:19.8 (J2000.0), offset
># = 4"W, 19"N) is a lenticular (S0) galaxy IC 522, which is thought to
># produce SN Ia only.  The expected maximum for typical SN Ia is mag
># about 16.0.  The spectral classification and the followup magnitude
># estimates are very urged.

  The CfA team has revealed that it is type Ia SN near maximum on Jan.
31.34.  They comment that it may be a subluminous event (Ti features
are stronger than normal).

SN 2003Z:
In [vsnet-campaign-sn 550] (Jan. 31):
>SN2003Z  20030120.7  <181:C  BAO
>SN2003Z  20030129.7   167C   BAO
>SN2003Z  20030130.4   165:C  KAI

># A host galaxy of SN 2003Z (9:07:32.46, +60:29:17.5 (J2000.0), offset
># = 9"W, 31"N) is a nearby open-spiral (SA(s)c:) galaxy NGC 2742.  The
># SN is superimposed on the outermost northern arm.  There is a
># foreground star (or a bright knot) 30" WNW of the nucleus of NGC
># 2742.  The expected maximum for typical SN Ia without extinction in
># NGC 2742 is 13.2 (!), but it seems not the case.

  Also the CfA team reported that it is type II SN.
