[vsnet-campaign-sn 446] types of recent SNe

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

Dear SN watchers,

  IAUC 7927 informs the spectral observations of recent SNe by the CfA
team.

SN 2002do:
In [vsnet-campaign-sn 442]:
># The host galaxy of SN 2002do is MCG +07-41-1, an elliptical (E1:)
># galaxy embedded in the Milky Way (b = 6.1 deg).  The expected
># maximum for typical SN Ia (the morphology of the host galaxy
># suggests this classification) is mag about 16.4.  

It is indeed of type Ia, near maximum on June 19.43 UT.  The Si II
absorption feature around 580 nm is strongly seen, which may indicate
that it is somewhat subluminous.

SN 2002dp:
In [vsnet-alert 7410]:
># SN 2002dp occured in a face-on spiral (SAB(rs)c;Sbrst Sy2) galaxy
># NGC 7678.  The position (measured by W. Li, the KAIT team) is: R.A.
># = 23h28m30s.12, Decl. = +22o25'38".8 (2000.0) , which is about 31"
># east and  22" north of the nucleus of NGC 7678 and superimposed on
># the northeastern arm.  The expected maximum for typical SN Ia is mag
># about 15.1.  SN Ib 1997dc also occured in the same galaxy, whose
># maximum was mag about 17.5.  

It is also of type Ia, near maximum on June 20.47 UT.  

SN 2002dq:
In [vsnet-alert 7410]:
># SN 2002dq occured in an early spiral (SB(r)a pec) galaxy NGC 7051.
># The position is R.A. = 21h19m49s.95, Decl. = -8o46'39".8 (equinox
># 2000.0), which is about 20" west and 19" north of the nucleus of NGC
># 7051.  There is a confusing foreground star about 40" NW of the
># nucleus, and SN locates between this star and the nucleus.  The
># expected maximum for typical SN Ia is mag about 14.8.

The spectrum taken on 20.42 shows that it is of type II.
