POSSIBLE NOVA IN SAGITTARIUS
Grzegorz Pojmanski et. al., of Warsaw University Astronomical 
Observatory have reported via VSNET Alert 11369 that the ASAS3V 
instrument of The All Sky Automated Survey (telephoto lens 200/2.8, 
diameter 70mm + CCD + Johnsons V  filter, 3 minute exposures, pixel size 
14.8 arcsec, rms astrometric accuracy - 4  arcsec) has detected a 
possible outburst of a nova located at:
RA 18h 07m 08s  DEC -33d 46'.6 (2000).

The object, designated by them as ASAS 180708-3346.6, was V=7.78 on 2009 
August 06. Several faint sources are present close to this position in 
the DSS image and USNO-B catalog, so no progenitor could be suggested 
based on the ASAS astrometry.
