MASTER-Net robotic telescopes (MASTER-Net: http://observ.pereplet.ru)
located  near Ekaterinburg (Kourovka)   was pointed to 
the Swift GRB 101008A (Saxton et al., GCN#11357) 22 s after Notice Time 
and 106 s after trigger time  at large zenit distance (80 degrees).

We have number  images in two perpendicular polarizations (along apha & 
dec) in V-band.

We have no found any OT.
