MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located in IAC (Tenerife, Spain) was pointed to the GRB150915A 22 sec
after notice time and 95 sec after trigger time at 2015-09-15 21:20:03 UT
in two polarizations. On our first single (20s exposure) and coadd (760s
exposure) sets we haven`t found optical transient within SWIFT error-box
(Elia et al. GCN 18315).
The 5-sigma upper limit has been about 17.3 on single and 19.8 on coadd
image.
