Subjects: Transient, Variables

The MASTER auto-detection system at Tunka (Baykal Lake) detected a new transient source at the position (R.A., Dec) = 16h 39m 42.75s , +12d 24m 14s.4, (J2000) with a typical uncertainty of 0.5" at 2011-06-04 18:34:49.39 (UT). The OT is seen at 2 images. There is CV type star inside error box B2=20.14 and R2=20.23 (USNOB).

The unfiltered (0.2B+0.8R) magnitude is about 16.4+-0.1 ( exposition 180s, mag limit =19.2). The spectral observations are needed.
