[vsnet-alert 4867] SN 2000cj in NGC 6753

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

Dear SN watchers,

  Sorry for one day+ delay.  The most famous (I guess) SN hunter Bob
Evans in Australia has visually discovered a bright SN in the southern
galaxy.  He has discovered the most SNe among the amateur astronomers,
though T. Puckett is now running closely after him.

  According to IAUC 7425, the discovery has made on May 14.7 UT when
the new object was mag about 14.8.  The position derived by R. H.
McNaught is: R.A. = 19h11m27s.68, Decl. = -57o03'19".4 (2000.0),
which is about 33" east and 20" south of the center of the host
face-on spiral ((R')SA(r)b) galaxy NGC 6753.  The new object is
embedded between the inner ring and outer faint ring (arm) of the
host.  

  There are several foreground stars that can lead to the confusion:
the brightest one is unfortunately not catalogued in USNO nor GSC.  It
is about 30" south of SN, and its rough position is: R.A. =
19h11m27s.5, Decl. = -57o03'49".  Another foreground star lies about
80" SW of the center of the host.  These two are both mag about 14.
SN watchers should take care in the SN identification.

  The recession velocity of the host (3124 km/s) suggest that the
normal SNeIa should reach about mag 14.8 at their maximum.  The
discovery magnitude suggest that this SN is surely intrinsically
bright object.  Followup photometry and spectroscopy (the type has not
been determined yet) is encouraged for this quite south object (it
cannot be followed up from Japan, I guess). 

Sincerely Yours,
