MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located in Kislovodsk was pointed to the GRB140108A 22 sec after notice
time and 39 sec after trigger time at 2014-01-08 17:19:21.913 UT in two
polarizations. On our first (10s exposure) set we haven`t found optical
transient within SWIFT error-box ( Racusin et al. GCN 15699 ).
The 5-sigma upper limit has been about 17.0 mag.
