Very Wide Field Camera of the MASTER  robotic system
(http://observ.pereplet.ru, 63.1x47.3 square degrees) imaged  HETE
fields-of-view before and after Probable GRB 060118 (TRIGGER_NUM:4006,
GRB_TIME: 85556.51 SOD {23:45:56.51} UT).

We analysed  images (3 s exposition, unfiltred)  before, during and
after  alert time.
There is no OT brighter than 8m (unfiltred, under the very cold Moscow
Moon night).
