MASTER OT J005415.49-615258.8 - possible SuperNova in PGC127812

MASTER-SAAO auto-detection system ( Lipunov et al., Advances in Astronomy, MASTER Global Robotic Net, 2010 ) discovered optical transient at (RA, Dec) = 00h 54m 15.49s -61d 52m 58.8s on 2015-02-23.78359 UT.

This possible SuperNova is 21"W and 36"N of the center of PGC127812 galaxy.

The OT unfiltered magnitude is 16.9m (the limit is 18.9m).

There are 3 images with OT on 2015-02-23. There is no minor planet at this place.

We have reference image without OT on 2015-01-22.79341 UT with 19.5 unfiltered magnitude limit in MASTER-SAAO database.

The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/MASTERJ005415.49-615258.8.jpg

Spectral observations are required.
