MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru) located in Kislovodsk was pointed to the GRB131122A 69 sec after notice time and 76 sec after GRB time at 2013-11-22 21:26:33.898 UT in two polarizations. On our first (20s exposure) set we haven`t found optical transient within INTEGRAL trigger N 6392 error-box (ra=10 11 02 dec=+57 38 22 r=0.054667). The polaroids have RA and DEC orientation on this observatory. The 5-sigma upper limit has been about 16.4 mag MASTER II robotic telescope located in Blagoveschensk was pointed to the GRB131122A 76 sec after notice time and 82 sec after GRB time at 2013-11-22 21:26:39.328 UT in two polarizations. On our first (20s exposure) set we haven`t found optical transient within INTEGRAL trigger N 6392 error-box (ra=10 11 02 dec=+57 38 22 r=0.054667). The polaroids are oriented under corners 45 and 135 to the RA axis on this observatory. The 5-sigma upper limit has been about 16.3 mag The message may be cited. The data reduction are continued.
