Dear CBAers,

This looks like a very interesting candidate for study, and pretty 
well-placed.  Unless it's a flat-liner, worth extensive study!


							     ATEL #3570

Subjects:Optical, Transient

The MASTER auto-detection system at Kislovodsk detected a new transient
source at the position (R.A., Dec) 23h 20m 22.36s , +44d 43m 30s.8 , (J2000)
with a typical uncertainty of 0.5" at 2011-08-17 23:10:15.502 (UT). The
OT also was seen at  images after ~45 min (2011-08-17 23:10:15 UT).
The unfiltered magnitude is about 15.9 +- 0.1 ( exptime 180s, mlim = 
18.0).  There is no minor planet or any object brighter 21 mag in DSS at 
this place.  We have a number images this field without OT with limit up 
to 19.0m.

The discovery and references images available here

Spectral observations are needed.
