Punanova Ural Federal University 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). This message can be cited.
