MASTER OT J083537.30-585738.0 discovery - PSN in PGC375031

MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 349171 ) discovered OT source at (RA, Dec) = 08h 35m 37.30s -58d 57m 38.0s on 2016-02-11.94799 UT.
The OT unfiltered magnitude is 15.8m (limit 19.4m).
The OT is seen in 14 images. We have reference image without OT on 2015-02-22.93765 UT with unfiltered magnitude limit 20.9m.
This PSN is in 16.6"W and 12.7"N from the center of PGC375031
Spectral observations are required.
The discovery and reference images are available at http://master.sai.msu.ru/static/OT/083537.30-585738.0.png
