[vsnet-campaign-sn 219] SN 2001dp in NGC 3493

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

Dear SN watchers,

>  Yesterday's IAUCs reported three discoveries of bright supernovae.
>I will make comments indivisually.

  The last one.  The members of the CROSS program in France (M.
Migliardi and E. Dal Farra) have discovered quite bright SN (mag 14.5)
on Aug. 12.9 UT.  It was confirmed on Aug 13.9, 14.83 UT by the
discoverers, and also on Aug 15.491 by Y. Sano.  The position is: R.A.
= 11h53m45s.22, Decl. = +52o20'56".8 (2000.0), which is about 35" west
and 80" north of the nucleus of the barred-spiral (SB(r)bc) galaxy NGC
3953.  There are several foreground stars so please take care in the
identification.  The discovery image
(http://vsnet.supernovae.net/sn2001/n3953s2.jpg) or the confirmation
image by Sano (http://vsnet3.ocn.ne.jp/~sanosn/2001sn/2001dp.html) would
help it.

  The spectroscopic confirmation was made at Bisei Astronomical
Observatory by K. Ayani and coleagues including visiting high school
students on the summer school.  The spectrum can be seen at

which suggest that it resembles to that of type Ia, around 1 month
after the maximum light.  NGC 3953 is nearby galaxy (roughly same
distance as the Virgo cluster), the expected maximum of the typical SN
Ia is mag 12.5.  So it can be brighter in the recent images.  If you
have imaged this galaxy in this summer, please check them.  Of course,
the follow-up observations are highly encouraged.

Sincerely Yours,
