MASTER  robotic telescope (MASTER-Net: http://observ.pereplet.ru, 200 mm, 
FOV=8 square degrees (testing mode)) and  Very Wide Field Camera (D=50 
mm, 1000 square  degrees, 11 Mpx, 36" per pix, mounted on telescope) 
located at Blagoveschensk   was ponted to the  GRB 100526A (L. Vetere et 
al. gcn 10797) 21 min after burst. For the unknown reason any of our 
observatories hasn't received socket alert on this burst (we have
received only auxiliary packages).

We have a number images with  60-s exposition.
We haven't found optical transient within Swift-XRT error-box.
The 3-sigma unfiltred upper limit has been about 17.0 mag on single and 
18.2 mag on 10 images coadd.
