MASTER-ICATE robotic very wide field cameras (FOV=2x384 square degrees, 
f/1.2, 1 pix = 22 arcsec, located in Argentina
(Observatorio Astronomico Felix Aguilar, were
pointed to the GRB120815A (C. Pagani, GCN 13645) 37 s after notice
time and 60 s after GRB time at 2012-08-15 02:13:58 UT. We haven`t found 
optical transient  within
SWIFT error-box  our first (5 s exposure) set. The 5-sigma upper limit has 
been about 12.0 mag
The 5-sigma upper limit on coadd first 30 images is about 13.0 mag.

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