MASTER  robotic telescope (MASTER-Net: http://observ.pereplet.ru, D= 200 
mm, FOV= 7  square degrees, 16 Mpx Apogee CCD, testing mode) located
at Blagoveschensk   was responted to the  GRB 091130
(Krimm et al., GCN 10212)   23 sec after Notice time and
7 min 22 s after the GRB time.

The first images are saturated due to the Moon light and cloudes.

After exposition correction we took several dozens succesfull images with 
limit ~14.5 mag.
