[vsnet-alert 5243] SN 2000dj in NGC 735

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

Dear SN watchers,

  The Lick KAIT team has discovered a mag 17 SN, which can reach 
over mag 16.  It seems to be on the rising phase.  

  They report on IAUC 7490 that the position is R.A. = 1h56m40s.63,
Decl. = +34o10'12".4 (2000.0), which is about 32" east and 24" south
of the nucleus of the tilted spiral (Sb) galaxy NGC 735.  On about 20"
northwest of the nucleus, a bright (mag about 13.5) foreground star is
there, and around the galaxy several stars (brightests are mag 10 and
11) and 2 accompanying eliptical galaxies are there.  

  The reported brightness (174:C at Sept. 8.4, 171:C at Sept. 9.4)
indicate that this SN is in the rising phase.  The expected maximum of
the typical SN Ia on this distance (v_r = 4629 km/s) is mag 15.7.  

  NGC 735 has produced another SN 1971L, which was m_pg = 15.0 at
discovery.  Referring the discovery photograph (Kowal et al., 1973,
PASP, 85, 427), it is quite close to the reported position of SN
2000dj.  Note that the position of SN 1971L in this paper and the
Asiago SN catalog (also in the NED) are insufficiently accurate, and
we need the current image of SN 2000dj to compare this reference image
of SN 1971L.  And, the brightness of SN 1971L is somewhat brighter as
a normal SN, so the different nature of this object can be minded.
The quick spectral confirmation and imaging of SN 2000dj are
especially encouraged. 

Sincerely Yours,
