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 GRB120802A (Holland et al, GCN 13555Not found
 
 
) 21 s after notice 
time and 43 s after GRB time at 2012-08-02 
08:01:34 UT under full Moon. We haven`t found optical transient  within 
SWIFT error-box  our first (5 s exposure) set.
The 5-sigma upper limit has been about 10.6 
mag The 5-sigma upper limit on coadd first 42 images is about 12.0 mag.

Our cameras are continuously imaging the sky with 5 sec exposures.
