MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located in SAAO was pointed to the GRB160411A 34 sec after notice time
and 64 sec after trigger time at 2016-04-11 01:30:00 UT. On our first (10s
exposure) set we haven`t found optical transient within SWIFT error-box
(Page et al GCN 19279, Evans et al GCN 19283).
The 5-sigma upper limit has been about 16.0 mag on single (10 sec
exposure) and 18.5 on coadd (170 sec exposure) image.
The observations made on high zenit distance (z=80 deg).
