MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located in Tunka was pointed to the GRB140311A 27 sec after trigger time
and 127 sec after trigger
time at 2014-03-11 21:07:23 UT in two polarizations. On our first (30s
exposure) set we haven`t found optical transient within SWIFT error-box
(Racusin et. al GCN 15944).
The 5-sigma upper limit has been about 16.27mag
MASTER II robotic telescope located in Blagoveschensk was pointed to the GRB140311A 10 sec after
notice time and 89 sec after trigger time at 2014-03-11 21:06:45 UT in
two polarizations.
On our first (20s exposure) set we haven`t found optical transient within
SWIFT error-box.
The 5-sigma upper limit has been about 14mag. The observations made on the
morning sky.
