MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located in Blagoveschensk was pointed to the GRB120211A (SWIFT trigger
514586; Sonbas et al. GCN 12920) 77 sec after GRB
time at 2012-02-11 11:59:45.629 UT. On our first (20s exposure) set we
haven`t found optical transient within SWIFT error-box (ra=05 51 00
dec=-24 45 36 ).
The 5-sigma upper limit has been about 16.3 mag.
