MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located in Tunka was pointed to the GRB130514B 90 sec after GRB time
but out first image were overlight by evening sky.
The first good image made 3812 sec after GRB time at 2013-05-14 14:30:06.562 UT.
On our first (180s exposure) good set we haven`t found optical transient
within INTEGRAL error-box (S.Mereghetti et. al GCN 14638).
The 5-sigma upper limit has been about 16.5 mag
The observations mae on large zenith distance z=83 deg.
