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 responted to the  GRB 100122A 
(Fermi-GBM  alert, TRIGGER_NUM: 285864459) 30 sec after first Notice time 
and 59 s after the GRB time . 
We have a number images with exposition from 5s to 180 s.
The image limit from telescope ~17m .
The image limit from Very Wide Filed Camera ~11.5.
Fermi GBM error box locate in   vicinity  Orion Nebula.
More accurate   error-box is required.
The image reduction is continued.

The one of the first nice images MASTER VWF camera (with Orion 
constalation and trees)  is available  at 
http://observ.pereplet.ru/images/GRB100122A/grb.html  .
