MASTER OT J055250.71-395431.6 - PSN or CV?

MASTER-SAAO auto-detection system ( Lipunov et al., Advances in Astronomy, MASTER Global Robotic Net, 2010 ) discovered OT source at (RA, Dec) = 05h 52m 50.71s -39d 54m 31.6s on 2015-10-17.07907 UT.The coordinates errors are aboute 0.5 arcsec.

The OT unfiltered magnitude is 17.9m (limit 20.1m). The OT is seen in 10 images. There is no minor planet at this place. We have reference image without OT on 2015-02-19.79562 UT with unfiltered magnitude limit 20.6m. There are no any objects in any catalogs at OT place. There are two galaxy near OT. The nearest one is PGC592423. The OT offset is 52E and 58.6N arcsecs.

Spectral observations are required.
