[vsnet-campaign-sn 502] SNe classifications

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

Dear SN watchers,

  IAUC 8014 informed the spectra of recent two SNe by the UCB team:
both spectra were taken on Nov. 9 UT with Keck II 10-m. 

SN 2002gz:
In [vsnet-obs 41955] (Oct. 20):
>SN2002gz  20020922.0  <202C  PAL
>SN2002gz  20021015.49  183C  PAL
>SN2002gz  20021018.0   182C  PAL
>
># SN 2002gz (2:34:10.36, -0:53:18.2, J2000.0) is located at about 4"
># east and 1" south of an apparent host dim galaxy.

  It is indeed a SN with a blue continuum and very broad undulations,
but the classification is uncertain.  It can be of type IIb because of
possible H-alpha emission and He I absorption.  The recession velocity
is measured as about 25000 km/s.

SN 2002ho:
In [vsnet-campaign-sn 498] (Nov. 9):
>SN2002ho  20020403.0   <185C  Bol
>SN2002ho  20021105.130  170C  Bol
>SN2002ho  20021107.528  168C  SCH
>
># NGC 4210, a host galaxy of SN 2002ho (12:15:17.97 +65:58:55.1
># (J2000.0), offset = 13"E, 12"S), is a barred-spiral (SB(r)b) galaxy.
># SN is superimposed on the southern arm.  Typical SN Ia in this
># galaxy would have a maximum of mag about 14.5, but it seems not the
># case for this SN.

  It is of type Ic within a few weeks after maximum.
