MASTER II  robotic telescope (MASTER-Net: http://observ.pereplet.ru) 
located in Tunka was pointed to the  GRB130508A 37 sec after notice time 
and 119 sec after GRB time at 2013-05-08 17:10:52.959 UT. On our first 
(20s exposure) set we haven`t found optical transients within SWIFT 
error-box (Holland et al. GCN14607).
The 5-sigma upper limit has been about 17.3 mag
