  MASTER II  robotic telescope (MASTER-Net: http://observ.pereplet.ru) 
located in Tunka(Siberia) was pointed to the  GRB110610.64 30 sec s after 
notice time and 55 sec after GRB time at 2011-06-10 15:22:27.062 UT. On 
our first (10s exposure) set we haven`t found optical transient  within 
SWIFT error-box (ra=20 32 35 dec=+74 49 11 r=0.050000).
  The 5-sigma upper limit has been about 15.0 mag
