MASTER II  robotic telescope (MASTER-Net: http://observ.pereplet.ru) 
located in Kislovodsk was pointed  to the  GRB120907A 375 s after notice 
time and 389  sec after GRB time at 2012-09-07 00:30:52  UT in a two 
polarizations.
We are marginaly see SWIFT-UVOT optical transient (J. L. Racusin et. al. 
GCN 13716) on out first images.
The unfiltred OT magnitude is about 17.5 mag.
The long pointing time  was due to some technical issues.
