[vsnet-alert 4052] SN 2000C in NGC 2415

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

Dear SN watchers,

  As IAUC 7348 informed, SN 2000C has been discovered on Jan. 8.789 UT
by an English astronomer S. Foulkes, and on Jan 12.95 UT by an Italian
astronomer M. Migliardi.  The report has been delayed about 10 days
(!) after its discovery.  

  The position derived from the discovery image is: R.A. =
7h36m57s.09, Decl. = +35o14'38".8 (2000.0), which is 8".3 east and
7".4 north of the nucleus of NGC 2415.  The position of nucleus was
measured on the same image, which has position end figures 56s.41,
31".4 (the uncertainty would be larger than 1" order; see below).  
Also W.D. Li, the LOSS KAIT term, provided the position of SN 2000C
end figures as 56s.99, 37".2, which agrees well with above.  

  The host galaxy is somewhat irregular one, having bright barred
nucleus (east to west) and surrounding disk.  The possible SN is
superposed on the northeastern part of the disk.  The eastern end of
the barred nucleus is possibly a foreground star, but the nature of it
is uncertain.

  As D. Bishop, ISN, has pointed out, SN 1998Y was observed on the
very near position of the current one.  The position of SN 1998Y was
reported as R.A. = 7h36m56s.93, Decl. = +35o14'36".0 (2000.0) on IAUC
6850.  The current one is slightly north and east of SN 1998Y, which
is shown on http://astron.berkeley.edu/~bait/2000/ngc2415.html . 

  The recession velocity of the host galaxy is about 3800 km/s, from
which the expected maximum of SNeIa on this galaxy is about 15.0 mag.
SN II 1998Y was observed as 18.3 mag.  The current SN seems a bright
SN like as SN Ia.  The followup spectroscopy and magnitude estimates
are urged.

Sincerely Yours,
