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.
