MASTER robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located in OAFA was pointed to the GRB170112A 18 sec after notice time
and 25 sec after trigger time at 2017-01-12 02:02:31 UT. On our first (10s
exposure) set we haven`t found optical transient within SWIFT
BAT error-box (Mingo et al., GCN 20436).
The 5-sigma upper limit has been about 16.04mag
