[vsnet-campaign-sn 85] SN 2000dk in NGC 382

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

Dear SN watchers,

  The Lick KAIT team has discovered a SN in the famous galaxy group.
Now it seems to be around the maximum and can be detected with a small
equipment with CCD.

  Reported on IAUC 7493, the location of SN 2000dk is R.A. =
1h07m23s.52, Decl. = +32o24'23".2 (2000.0), which is about 5" west and
9" north of the nucleus of the elliptical galaxy NGC 382.  It was mag
about 15.8 on Sept. 19.2 UT, and no confusing foreground star are
there at this magnitude.  

  NGC 382 is interacting with the bigger lenticular galaxy (SA0) NGC
383, which locates about 30" NNE of NGC 382.  It is a small problem
which of them is a true host galaxy.  The angular separation between
the SN from the nucleuses of these two galaxies are about 9" from NGC
382, and 28" from NGC 383.  According to the recession velocity (see
below), one arcsecond coincidents to about 380 (H_0/65) pc.  They are
the brightest members of the group of the galaxies named as "Pisces
cloud", and this group is included by the elongated "Perseus-Pisces
Super Cluster".  

  The recession velocity of NGC 382 indivisual is 5228 km/s, but the
one for the Pisces Cloud seems to be slightly small as around 4800
km/s.  Typical SNeIa on this distance would be mag 15.7 at their
maximum.  The follow-up photometry of this SN would be useful for
exploring the nature of it, as well as the spectroscopic
identification. 

Sincerely Yours,
