  The UCB team took spectra of three recent SNe on Feb. 4.

SN 2003X:
In [vsnet-campaign-sn 550] (Jan. 31):

># A host galaxy of SN 2003X (18:12:05.67, +29:09:17.3 (J2000.0),
># offset = 1"E, 4"S) is a tilted spiral galaxy UGC 11151.  It is
># elongated in north-south direction, and SN is located at the edge of

  It is of type Ia, resembling SN Ia 1994D about a month after
maximum.  It may be somewhat luminous than typical one.

SN 2003ab:
In [vsnet-campaign-sn 552] (Feb. 4):
>SN2003ab  20030411.0   <190C  Bol
>SN2003ab  20030201.971  178C  Bol
>SN2003ab  20030202.856  178C  Bol
>
># A host galaxy of SN 2003ab (9:19:13.26, +48:58:09.1 (J2000.0),
># offset = 9"E, 4"N) is UGC 4930, a distant spiral (Scd:) galaxy.
># There is a bright (mag about 12) foreground star about 40" ENE of
># the nucleus of UGC 4930.  The SN is located between this star and
># the nucleus.  The expected maximum for typical SN Ia is mag about
># 17.1.  

  It is type II SN within a few weeks after the explosion.

SN 2003ac:
In [vsnet-campaign-sn 552] (Feb. 4):
>SN2003ac  20020517.3 <195:C  KAI
>SN2003ac  20030107.5  189:C  KAI
>SN2003ac  20030120.4  189:C  KAI
>SN2003ac  20030202.5  189:C  KAI
>SN2003ac  20030203.4  189:C  KAI

># A host galaxy of SN 2003ac (12:21:47.35, +25:52:33.1 (J2000.0),
># offset = 23"E, 31"S) is IC 3203, an edge-on spiral (Sb) galaxy.  It
># is superimposed on the disk.  The expected maximum for typical SN Ia

  It is also of type II.  They add the resemblance with SN II 1987K.
