MASTER-IAC robotic telescope (MASTER-Net: http://observ.pereplet.ru) 
located in Teide observatory was pointed to the Fermi LAT
GRB160816A  924 sec after notice time at 2016-08-16 22:57:12 UT 
(NOTICE_DATE:Tue 16  Aug 16 22:42:36 UT)  and 19665 sec after the trigger 
time(the delay in 15min was from the inspection of previous FermiGBM 
alert and late notice time).

  On our first  180s exposures we haven`t found optical transient  within
  LAT error-box (RA, Dec = 322.45, 37.16 (J2000) r=0.13).

There is a disc galaxy (unknown in NED) inside LAT error-box at the 
position 21h 29m 23.16s +37d 05m 54.9s - possible host galaxy for GRB.

The 5-sigma upper limit has been about 19.7 mag
