MASTER II  robotic telescope (MASTER-Net: http://observ.pereplet.ru) 
located in Kislovodsk was pointed to the  GRB141026A 22 sec after notice 
time and 99 sec after trigger time at 2014-10-26 02:38:31 UT in two 
polarizations. On our first single and coadd images we haven`t found 
optical transient  within SWIFT error-box (Hagen et. al. GCN 16950). The 
5-sigma upper limit has been about 16.5 on single (20s exposure) and 17.5 
on coadd image (from first 3 images with total exposure 80 sec). The 
message may be cited.
