MASTER II  robotic telescope (MASTER-Net: http://observ.pereplet.ru) 
located at Kislovodsk was pointed to the  GRB101112A 21 sec s after 
notice time and 36 sec after GRB time at 2010-11-12 22:11:11.00 UT at 
very high zenit distance (~88 degrees).
On our first (10s exposure) set we haven`t found optical transient  within 
UNDEF error-box (ra=19 29 16 dec=+39 23 22 r=0.047500).

The 5-sigma upper limit has been about 15.7 mag

We have no found any OT at Liverpool OT position (Guidorzi et al., GCN 
Circ 11397).
