MASTER II robotic double telescope (MASTER-Net:
http://observ.pereplet.ru) located in Blagoveschensk was pointed
to the GRB111228.66 191 sec after notice time and 244 sec after
GRB time at 2011-12-28 15:48:47.127 UT. The some delay was due to weather conditions.
On our first (20s exposure, two polarizations, unfiltered) set we found
optical transient at Swift OT position (Ukwatta et al., GCN Circ R12737).
The OT magnitude is about 16.5 mag in both polarizations.
The reduction is continuated.
