[vsnet-alert 7267] SN 2002bx in IC 2461

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

Dear SN watchers,

  The KAIT team and Tom Boles has discovered a probably rising nearby
SN in the galaxy on the border of Lyn-LMi.  The expected maximum for
typical SN Ia is mag about 14.0.

  SN 2002bx is discovered by the KAIT team on Mar 31.2 at mag about
16.9, and confirmed on the next night (mag 16.8).  Tom independently
discovered it on Apr. 1.943, when he estimated the magnitude as 16.2.
The position of the new object (the KAIT measurement) is: R.A. =
9h19m54s.98, Decl. = +37o12'08".3 (2000.0), which is about 37" west
and 40" north of the nucleus of the edge-on spiral (Sbc) galaxy IC
2461.  The SN is almost superimposed on, but slightly (2-3") south of,
the disk plane.  No confusing foreground star are there.  Several mag
15 stars are around the galaxy, but because of their redness, take
care in choosing the comparison stars in the magnitude estimates.

  The recession velocity of IC 2461 is measured as 2260 km/s.  The
Galactic extinction is negligible.  If it is unreddened by the
interstellar matter in the host galaxy, the expected maximum for
typical SN Ia is mag about 14.0.  The spectroscopic classification and
the followup magnitude estimates are urged.

Sincerely Yours,
Hitoshi Yamaoka, Kyushu Univ., Japan
