Just in case nobody has already confirmed, hereby my observed particualrs
for the new bright object reported by Bill:

filtered CCD photometry

N Sgr05?   20050705.08   7.4V
N Sgr05?   20050705.08   7.2Rc

These magnitudes are possibly fainter than the true ones due to saturation
on the images.


Position (2000) vs Tycho stars:

18 17 50.45 -30 26 35.1 (+/- 0.15 arcsec estimated)

USNO-B1.0 shows the following stars within the uncertainty area:

0.1378  18 17 49.83  -30 26 37.0  0595-0712219  1975.1    3  20.35
18.02  23.13
0.1109  18 17 50.96  -30 26 34.2  0595-0712297  1972.9    5  16.04  15.31
16.41  16.05  14.22
0.1371  18 17 51.03  -30 26 38.5  0595-0712305  1972.5    4  18.21  18.12
18.87  17.63

Due to the blue colour and the possibility of the nearest candidate being
the progenitor this might be an outbursting CV, but the brightness increase
of at least 8 magnutdes might hint at a nova...
