MASTER II  robotic telescope (MASTER-Net: http://observ.pereplet.ru) located in 
Tunka(Siberia) was pointed to the  GRB110411A (Grupe et al., GCN 11918) 19 
sec s after notice time and 44 sec after GRB time at 2011-04-11 19:34:55.3 UT in two polarizations.
A series of Polarization, White and R-band images were obtained.
We have not found OT at Xinglong TNT OT candidate position (Xin et al., GCN Circ 11923). 
The results from two tubes are:
