[vsnet-campaign-sn 515] SNe classifications

[Hitoshi YAMAOKA <yamaoka@rc.kyushu-u.ac.jp>]

Dear SN watchers,

  IAUC 8027 informed the classification of four recent SNe by Baade
telescope at Las Campanas.

SN 2002ia:
In [vsnet-campaign-sn 507] (Nov. 18):
>SN2002ia  20011111.0  <200:C  NEM
>SN2002ia  20021030.53  192C   NEM
>SN2002ia  20021113.0   186C   NEM
>SN2002ia  20021114.0   185C   NEM
>
># A host galaxy of SN 2002ia (1:45:38.52, +24:08:07.9 (J2000.0),
># offset = 4"W, 4"N) is anonymous and quite dim (USNO rmag is 19.1).
># Its appearance on the DSS image suggest that it is possibly a spiral
># galaxy. 

  It was a type Ia SN about 2-3 weeks after maximum on Nov. 29.13.
The redshift of SN 2002ia was measured as about 0.072.

SN 2002ib:
In [vsnet-obs 42357] (Nov. 21):
>SN2002ib  20021003.0  <212C  PAL
>SN2002ib  20021031.21  198C  PAL
>SN2002ib  20021112.0   182C  PAL
>SN2002ib  20021113.0   181C  PAL
>SN2002ib  20021119.0   183C  PAL
>
># A host galaxy of SN 2002ib (0:54:07.45, +17:33:53.7 (J2000.0),
># offset = 1"E) is a very dim object and hardly seen on the DSS.

  It was also a type Ia SN about 10 days after maximum on Nov. 29.10.
The redshift of SN 2002ia was measured as about 0.068.

SN 2002jf:
In [vsnet-obs 42396] (Nov. 25):
>SN2002jf  20021026.0 <210C  PAL
>SN2002jf  20021030.0  197C  PAL
>SN2002jf  20021101.0  194C  NEM
>SN2002jf  20021106.0  188C  NEM
>SN2002jf  20021112.0  178C  PAL
>SN2002jf  20021122.0  187C  PAL
>
># A host galaxy of SN 2002jf (2:34:35.43, +12:17:25.4 (J2000.0),
># offset = 3"E, 1"S) is a dim galaxy (USNO_A2.0 rmag = 18.6) with a
># possibly spiral nature.  It possibly belongs to a distant cluster as
># well as neighbouring dim galaxies.

  It was again a type Ia SN about 2-3 weeks after maximum on Nov.
28.19.  The redshift of SN 2002ia was measured as about 0.079.
Probably a luminous event.
  
SN 2002jh:
In [vsnet-obs 42445] (Nov. 30):
>SN2002jh  20021031.0  <204C  PAL
>SN2002jh  20021112.48  184C  PAL
>SN2002jh  20021112.49  184C  PAL
>SN2002jh  20021112.52  184C  PAL
>SN2002jh  20021115.0   183C  PAL
>SN2002jh  20021117.0   185C  PAL
>SN2002jh  20021125.0   186C  PAL
>
># A host galaxy of SN 2002jh (4:27:29.57, +06:01:34.2 (J2000.0),
># offset = 5"E, 3"S) is an anonymous disk galaxy.  

  It was one more type Ia SN about 10 days after maximum on Nov.
28.23.  The redshift of SN 2002ia was measured as about 0.048.
It was somewhat subluminous or reddened.
