MASTER OT J095503.19-355149.4 discovery - possible optical counterpart of Fermi trigger 478121069
MASTER-SAAO auto-detection system( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L )
discovered OT source at (RA, Dec) = 09h 55m 03.19s -35d 51m 49.4s on 2016-02-25.89505 UT during Fermi trigger 478121069 inspection (Buckley et al., GCN #19092).
The OT unfiltered magnitude is 18.1m (the limit is 19.3m).
The OT is seen in 3 images. There is no minor planet at this place.
We have reference image without OT on 2015-01-17.92448 UT with unfiltered
magnitude limit 19.7m.
There are no known sources in VIZIER database at these coordinates, so in any case the outburst amplitude is more then 4m (22m POSS limit)
Spectral observations are required.

The OT position inside last error box (very close to center) is available
