[vsnet-alert 6316] SN 2001do in UGC 11459

[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 second one is the KAIT discovery reported on IAUC 7682.  It was
discovered on Aug 14.2 at mag about 16.2, and confirmed the next day
when it was mag about 16.1.  A previous KAIT image taken on Aug 10.2
did not show this object, so it would be fresh object.  The position
is R.A. = 19h37m23s.02, Decl. = +40o42'24".3 (2000.0), which is about
5" east and 4" north of the nucleus of the open spiral (Sd) galaxy UGC
11459.  Note that the precise position reported on IAUC 7683 seems to
be erronous (about 3").  

  Because of low galactic latitude (b = 9o.4), there are many
foreground stars (or blobs or companions?) around this galaxy.
Several nearest ones to the nucleus are not catalogued in USNO_A2.0.  
In the northeastern part of UGC 11459, three objects are there:

    R.A. (2000.0) Decl.     rough rmag.  offset from nucleus
19h37m23s.07 +40o42'33".3      16.0       12"N,  6"E
      23s.67        23".6      17.0        3"N, 12"E
      23s.97        28".6      17.0        8"N, 16"E

Please take care in the identification of SN.  The discovery image can
be seen at: http://astron.berkeley.edu/~bait/2001/sn2001do.html .

  The recession velocity of UGC 11459 is about 3100 km/s, so the
expected maximum of typical SN Ia is around mag 15.5 after the
correction of the Galactic extinction.  The photometric follow-up and
the spectroscopic confirmation is surely encouraged.

Sincerely Yours,
