The MASTER auto-detection system at Kislovodsk detected a new transient source at the position (R.A., Dec) 01h 32m 41.20s , +34d 38m 09s.1, (J2000) with a typical uncertainty of 0.5" at 2010-12-09 16:31:09 (UT). The OT was seen at next image after ~45 min (2010-12-09 17:17:24 UT). There is now minor planet and any object brighter 21 mag in DSS at this place. We have a number images this field without OT. The one was made at 2009-10-14 21:38:56 and have the limit 19.0 (5 hours before detection).

The unfiltered magnitude is about 17.7 +-0.1 ( exposition 180s, mlim = 19.4 ).

There is significant fading OT on the late images 4 weeks:

The unfiltered magnitude at 2011-01-06 19:54:48 is about 18.8 +-0.2 ( exposition 180s, mlim = 19.2 ).

The spectral observations are needed.
