MASTER OT J081506.13+381123.3 discovery - PSN in 11"E,2.8"N of PGC2120251

MASTER-Kislovodsk auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 08h 15m 06.13s +38d 11m 23.3s on 2017-01-16.01742 UT.
The OT unfiltered magnitude is 16.9m (limit 18.6m).
The OT is seen in 2 images in MASTER-Kislovodsk and in 2 in MASTER-SAAO (2017-01-18 00:38:36UT).
There is no minor planet at this place.
We have reference image without OT on 2016-11-29.91344 UT with unfiltered magnitude limit 20.1m.
Spectral observations are required.
