[vsnet-campaign-sn 441] types of recent SNe

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

Dear SN watchers, 

  IAUC 7920-22 reported some spectra of recent SNe.

SN 2002di: 

In [vsnet-obs 40219]:
># The host galaxy of SN 2002di is MCG +05-40-2, which is a distant
># interacting galaxy.  The expected maximum for typical SN Ia is mag
># about 17.6.

  It is of peculiar (subluminous) SN Ia, roughly 1 week after maximum
on June 17 (the UCB team, IAUC 7920).

SN 2002dk:

In [vsnet-obs 40238]:
># NGC 6616 = the host galaxy of SN 2002dk is a spiral (Sab) galaxy
># somewhat near to the Galactic plane (b = 17o).  The position is:
># R.A. = 18h17m43s.52, Decl. = +22o14'53".4 (2000.0), which is about 
># 34" east and 35" north of the nucleus of NGC 6616.  The expected
># maximum for typical SN Ia is mag about 16.5.

  It is also of peculiar SN Ia near maximum on June 17 (ibid).

SN 2002dg:

In [vsnet-campaign-sn 434]:
># This SN was discovered during the course of the NEAT survey.  The
># apparent host galaxy is quite dim and unnamed.

  The Padova team took a spectrum of SN 2002dg with ESO NTT at La
silla on June 15.13, which reveals that it is type Ib SN, 2-3 weeks
after maximum.  The recession velocity of the host galaxy is measured
as 14000 km/s.
