MASTER II  robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located in Blagoveschensk was pointed to the  GRB151001B   20 sec after
notice time and 96 sec after trigger time at 2015-10-01 18:31:13 UT. On
our first (20s exposure)  set we haven`t found optical transient  within
SWIFT error-box (Krimm et. al GCN 18374).
The 5-sigma upper limit has been about 18.0 mag
