I've posted a single-night UBVRI field photometry file
for this object at
ftp://ftp.nofs.navy.mil/pub/outgoing/aah/sequence/nmon02.dat
The actual photometry of the possible nova itself is:
  RA (J2000) DEC          HJD       V     B-V    U-B    V-R    R-I
106.020068  -3.847484  52285.7223  9.975  1.726  1.916  0.943  0.931
with internal astrometric errors of about 100mas and external
photometric errors of about 0.03mag due to the poor seeing.
((U-B) is more suspect than the other colors because of the
crowded field.)  This does not look nova-like to me.
