MASTER OT J113841.74+275059.1 discovery - PSN in 7.8" of the center of SDSS J113842.29+275056.4 edge-on (Sc?) galaxy

MASTER-IAC auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L )
discovered OT source at (RA, Dec) = 11h 38m 41.74s +27d 50m 59.1s on 2017-12-26.11289 UT.
The OT unfiltered magnitude at discovery time is 17.7m (limit 19.6m).
The OT is seen in 6 images. There is no minor planet at this place.
This PSN is in 7.8" of edge-on, possibly Sc (not classificated yet), Sloan galaxy.
We have reference image without OT on 2016-05-30.88508 UT with unfiltered magnitude limit 20.3m.
Spectral observations are required.
