MASTER OT J223724.76-383650.4 discovery - PSN in 19.4" of GALEX galaxy (PGC607013)

MASTER-OAFA auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 22h 37m 24.76s -38d 36m 50.4s on 2016-12-28.04038UT
The OT unfiltered magnitude is 18.3m (limit 19.0m).
The OT is seen in 3 images. There is no minor planet at this place.
We have reference image without OT on 2016-08-02.22922 UT with 20.3m unfiltered magnitude limit .
There is PGC607013 in 19.4", also known as GALEXASC J223724.32-383710.3, 6dFJ2237243-383709, etc
Spectral observations are required.
