MASTER OT J001858.94-402211.9 discovery - posible supernova in PGC587150 galaxy

MASTER-SAAO auto-detection system ( Lipunov et al., Advances in Astronomy, MASTER Global Robotic Net, 2010 ) discovered OT source at (RA, Dec) = 00h 18m 58.94s -40d 22m 11.9s on 2015-10-13.86418 UT.

The OT unfiltered magnitude is 17.0m (the limit is 20.3m).
The OT is seen in 2 images. There is no minor planet at this place. We have reference image without OT on 2015-08-17.02949 UT with unfiltered magnitude limit 19.7m.
This PSN is in 9.7"W and 11"N from the center of PGC587150 galaxy (110Mpc)with Bmag=16.5(+-0.4), Imag=16.3(+-0.1) Spectral observations are required.

The discovery and reference images are available at http://master.sai.msu.ru/static/OT/MASTEROTJ001858.94-402211.9.jpg
