MASTER II  robotic telescope (MASTER-Net: http://observ.pereplet.ru) 
located in Blagoveschensk was pointed to the  GRB140930B 21 sec after 
notice time and 39 sec after trigger time at 2014-09-30 19:42:21 UT in two 
polarizations. On our first (10s exposure)  set we haven`t found optical 
transient  within SWIFT error-box (ra=00 25 25 dec=+24 16 28 r=0.050000).
The 5-sigma upper limit has been about 16.0 mag


MASTER II  robotic telescope (MASTER-Net: http://observ.pereplet.ru) 
located in Kislovodsk was pointed to the  GRB140930B 36 sec after notice 
time and 54 sec after trigger time at 2014-09-30 19:42:36 UT  in two 
polarizations. On our first (10s exposure)  set we haven`t found optical 
transient  within SWIFT error-box (ra=00 25 25 dec=+24 16 27 r=0.050000).
The 5-sigma upper limit has been about 15.5 mag

The observations on both observatories is continued.
