MASTER-IAC  robotic telescope (MASTER-Net: http://observ.pereplet.ru, 4 
square degrees twin telescope) 
located in IAC was pointed to the  GRB160714A (Siegel et al., GCN 19697) 
26 sec after notice time and 50 sec after trigger time at 2016-07-14
02:20:05 UT. On our first (10s exposure)  set we not  found optical
transient within SWIFT error-box (ra=15 37 50 dec=+63 49 51 r=0.05 degrees)
brighter then 16.1.

Our automatic results of the first 20 minutes observations after trigger 
tieme are:
