MASTER II  robotic telescope (MASTER-Net: http://observ.pereplet.ru) 
located in SAAO automaticaly was starting survey on the FERMI  GRB150702A 
error-box (ra=03 34 31 dec=-57 43 12 r=1.110000)  4575 sec after notice time and 
4708 sec after trigger time at 2015-07-03 01:15:06 UT. The 5-sigma upper 
limit on our first (60s exposure)  set is about 18.0 mag
Any uncatalogued optical sources inside Fermi-LAT error box (Evans et 
al., GCN 17990)  detected in this 
observations. No OT detected at XRT Source 1 and 2 positions (D'Avanzo 
et al., GCN 17991).
