MASTER II robotic double telescope (MASTER-Net:
http://observ.pereplet.ru) located at Tunka (Baykal) was pointed to the
120106A (Immler et al., GCN Circ 12810) 19 s after notice time and 46 sec
after GRB trigger time at 14:16:24.24 UT (Ivanov et al., GCN CIRC 12811).
On our first (10s exposure) set we haven`t
found optical transient within preliminary SWIFT XRT error-box (Immler
et al., GCN Circ 12810).
But we found marginally OT at East telescope (- polarizations) outside
preliminary X-ray error box (Immler et al., GCN Circ 12810). The position
of this OT is coincided with enhanced Swift-XRT position (Evans et al.,
GCN CIRC 12813).
