Four MASTER   robotic systems (MASTER-Net: http://observ.pereplet.ru, 6 
Very Wide Field cameras and 3 Wide Field Telescopes ) 
located  near Kislovodsk and Tunka (near Baykal Lake)   was pointed to the 
GRB 100718A (Fermi trigger Number 301172784).
Initially all Very Wide Field Cameras are closed to Fermi GBM error box.
So we have next table of the observations:

* FOV axb, a - along r.a.

The weather was not very good at both sites.
We wait the more accurate error box.
