MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru)
located in Kislovodsk was pointed to the GRB110106A (Mangano et al., GCN
Circ 1152) 17 sec s after notice time and 41 sec after GRB time at
2011-01-06 15:25:57.96 UT in two polarizations+filter R. On our
first (10s exposure) set we haven`t found optical transient within SWIFT
XRT error-box.
The 5-sigma upper limit has been about 16.0mag
We marginally see OT about 15.5 mag in XRT error box on second set at
2011-01-06 15:26:19 (starting 69 s after trigger time with 10 sec
exposition).
We see the like galaxy object near (~15" distance) XRT error box ~19-20
mag on later images. But, there is no object in NASA/IPAC EXTRAGALACTIC
DATABASE.
The same object is presented at DSS image.
The redaction is continueted.
