[vsnet-campaign-sn 536] SN Ib 2003H

Dear SN watchers,

SN 2003H:
In [vsnet-campaign-sn 532] (Jan. 10):
>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).   

  IAUC 8047 informed that spectra taken with Baade-6.5m telescope on
Jan. 9 and 10 UT reveal that it is type IIb SN.  It resembles SN Ib
1984L before maximum light, but much more red probably due to its
intrinsic color. 

Sincerely Yours,
Hitoshi Yamaoka, Kyushu Univ., Japan
