MASTER-SAAO  robotic telescope (MASTER-Net: http://observ.pereplet.ru) 
located in SAAO was pointed to the  GRB160712.83 26 sec after notice time 
and 48 sec after trigger time at 2016-07-12 19:54:28 UT. On our first (10s 
exposure)  set we haven`t found optical transient  within SWIFT error-box 
(ra=20 16 35 dec=-26 58 52 r=0.050000).
The 5-sigma upper limit has been about 16.7 mag
