MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located in Kislovodsk was pointed to the Swift GRB121001A 43 s after
notice time and 209 sec after GRB time at 2012-10-01 18:26:31 UT in a
two polarizations.
We haven`t found optical transient within SWIFT error-box (D'Elia
et al. GCN 13831) on our first (20 s exposure) set.
The 5-sigma upper limit has been about 15.8 mag
Observations were carried out under the full moon and on high zenith
distance (~70 deg). Also a high stars density complicates the analysis.
The data reduction is continued.
