Possible Nova in Pup: astrometry update

     R.A. (J2000)  Decl.
  07 37 56.91  -25 56 59.7  H. Abe, GSC-ACT (vsnet-alert 5492)
  07 37 56.91  -25 56 59.0  G. Masi, Kyoto image, USNO A2.0 (vsnet-alert 5494)
  07 37 56.880 -25 56 58.89 K. Kadota, GSC-ACT (vsnet-alert 5497)
  07 37 56.88  -25 56 58.8  A. Henden, UCAC1 (vsnet-chat 3932)

As I promised, I've updated the astrometry
in this field using UCAC1.  The field photometry file at
http://ftp.nofs.navy.mil/pub/outgoing/aah/sequence/npup00.dat
now has improved astrometry (the photometry remains the same).
In particular, the nova candidate can be found at:
  RA (J2000)  DEC         RA          DEC        V     B-V    V-R    R-I
114.487000 -25.949680  07:37:56.88 -25:56:58.8  9.090  0.564  0.475  0.758

There is a UCAC1 star at:
   RA (J2000)    DEC         mag
07 37 56.882  -25 56 58.85  13.60

So the nova candidate and this star are identical within error
(less than 100mas).  This is a *very* small magnitude range for
a nova.
