[vsnet-campaign-sn 263] SN 2001ew in anonymous galaxy

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

Dear SN watchers,

  In the course of UK Nova/SN patrol, Tom Boles has discovered a SN
in a dim galaxy within the region of Abell 426 = "Perseus cluster".  
The magnitude at discovery (Oct. 9.133) was mag about 17 (unfiltered
CCD), and has somewhat brightened in a following week.  

  The position of the new object, measured by Mike Armstrong, is R.A.
= 3h13m07s.46, Decl. = +42o26'14".9, which is about 5" due east of the
nucleus of the anonymous spiral host galaxy.  Tom has also reported
the position of this object, but it seems to be consistent with the
position of the nucleus of the host galaxy.  

  Because of the low galactic latitude (b = 13o), there are several
foreground stars around this galaxy.  One star is located on about 11"
east and 1" south of the nucleus of the host galaxy.  The SN locates
on the midway of this foreground star and the nucleus (slightly north
of this line). 

  The host galaxy is near to UGC 2590, which is a member of the
"Perseus Cluster" Abell 426.  If the host galaxy is also a member of
this cluster, the expected maximum of typical SN Ia is mag around 16
(included the Galactic extinction but not of the host).  It is also 
possible that it is the far behinder.  The spectral confirmation and
the continuous photometry is urged.

Sincerely Yours,
Hitoshi Yamaoka, Kyushu Univ., Japan
