[vsnet-campaign-nova 130] Possible Nova in Pup: astrometry update
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.
