MASTER-Amur auto-detection system discovered OT source at (RA, Dec) = 10h 51m 23.02s +67d 25m 28.3s on 2012-01-01.70 UT. The OT magnitude in 'V' filter is 14.6 m (limit is about 18.0m)

The OT is seen at 5 images.

We have reference image with low state OT on 2011-11-30.97 UT with unfiltered magnitude ~18.5m.

There is X-ray (ROSAT), radio (ARXA) and optical (the blue USNO-A2.0 star) object at this place.

The discovery image is available at http://observ.pereplet.ru/MASTER105123.02+672528.3/MASTER105123.02+672528.3.png .

Follow up radio, X-ray and optical spectral observations are required.
