# A host galaxy of SN 2003W (9:46:49.48, +16:02:37.6 (J2000.0), offset
# = 3" due north) is a spiral (S(r)c) galaxy UGC 5234.  There is a
# very bright (mag about 11) foreground star about 20" due east of the
# nucleus of UGC 5234.  The CfA team took a spectrum on Jan. 29.34,
# which revealed that it is type Ia supernova well (about 12 days)
# before maximum.  The expected maximum for typical SN Ia is mag about
# 16.3, if an extinction within the host galaxy is small.

># A host galaxy of SN 2003U (17:22:45.66, +62:09:50.4 (J2000.0),
># offset = 13"E, 7"S) is a face-on barred-spiral (SBcd) galaxy NGC
># 6365A, which is making a probably interacting pair NGC 6365 = Arp 30

  The CfA team also revealed that It is a type-Ia SN a few days before
maximum light on Jan 29.53.
