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 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.
