[vsnet-campaign-sn 179] SN 2001bg in NGC 2608

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

Dear SN watchers,

  An English amateur SN hunter T. Boles has discovered a bright SN in
the evening sky.  It is now at mag 14.  

  SN 2001bg was discovered on May 8.943 when it was mag about 14.  The
next day it was confirmed at the nearly same magnitude.  The reported
position is R.A. = 8h35m18s.86, Decl. = +28o28'05".8 (2000.0), which
is 22" east and 19" south of the center of the barred-spiral (SB(s)b:)
galaxy NGC 2608.  It locates southeastern part of the galaxy, outside
of the arm region.  

  Superimposed on the bar of the host galaxy, there is a bright (mag
about 14.5) star, which apparently makes it as having "double
nucleus".  The southeastern "nucleus" is a real one, and the
northwestern one is a foreground star.  The angular distance of these
two is about 7".  SN 2001bg locates far southeast.  

  NGC 2608 is somewhat nearby galaxy.  Its recession velocity is about
2100 km/s.  de Vaucouleurs and Peters (1984 ApJ, 287, 1) lists this
galaxy as m-M = 31.24, nearly the same as the Virgo cluster.  And,
this galaxy produced another SN 1920A, which was observed as mag about
12.0.  This magnitude is slightly brighter than the typical SN Ia
maximum in the Virgo cluster.  The contact follow-up photometry and
type determination is highly urged for this nearby SN 2001bg.

Sincerely Yours,
