MASTER-ICATE robotic very wide field cameras (FOV=2x384 square degrees, 
D=72mm, f/1.2, 1 pix = 22 arcsec, http://observ.pereplet.ru) located in 
Argentina (Observatorio Astronomico Felix Aguilar, 
http://93.180.27.230:8080/) were pointed to the FERMI trigger 
368003226 18 s after notice time and 44 s after GRB time at 2012-08-30 
07:07:47 UT.
We cover full 1-sigma and part of 3-sigma FERMI error-box  (76.836d, 
-27.824d error 2.99)
We haven`t found  optical transient  within FERMI error-box  our first (5 
s exposure) set and on coadd image made of 60 images and complete exposure 
of 300 seconds.
The coverage map is available 
http://master.sai.msu.ru/static/GRB120830_covermap.jpeg
The 5-sigma upper limit on single image has  been about 11.0 mag and 12.0 
mag on 
coadd image.
Our cameras are continuously imaging the sky with 5 sec exposures.
Weather conditions were not so good (feeble cloudiness).
