[vsnet-alert 5864] SN 2001bf in MCG +04-42-22

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

Dear SN watchers,

  An English amateur has discovered a bright SN.  It is now in a
rising phase at mag 16.

  IAUC 7620 reports that the discovery of SN 2001bf was made by M.
Armstrong on May 3.02 at mag 16.5, and he confirmed it on May 4.965 at
mag 15.9.  The reported position is R.A. = 18h01m33s.99, Decl. =
+26o15'02".3 (2000.0), which is 5" east and 8" south of the center of
the spiral (?) galaxy MCG +04-42-22.  Because of somewhat low galactic
latitude (21o), there are some foreground stars neighbouring the
galaxy, but the SN is very close to the nucleus of the host galaxy.

  From the recession velocity of the host galaxy (4647 km/s from NED),
the expected maximum of the typical SN Ia would be 15.9 mag or so
(considering the Galactic extinction A_V about 0.3).  The follow-up
photometry of this bright SN is encounraged, as same as the
spectroscopic classifications.

Sincerely Yours,
Hitoshi Yamaoka, Kyushu Univ., Japan
