GCN 18229) 67 sec after trigger time at 2015-09-02 17:36:47 UT. On our first (10s exposure) set we not found optical transient within FERMI error-box (ra=16 24 36 dec=-72 54 35 r=2.140000) brighter then 15.27. MASTER-SAAO robotic telescope makes several alert and inspect observations inside actual (at that time) FERMI GBM error boxes, but all of that frames located far away from the final FERMI LAT (Arimoto et. al GCN 18228) error box and did not cover it. MASTER-VWF very wide fileld cameras placed in MASTER-SAAO cover FERMI LAT error box at 2015-09-02 17:36:32.0 i.e. 47 sec after notice and 53 sec after trigger time, and imaging it continuously without time gaps till 2015-09-02 17:43:00. We have not find OT inside FERMI LAT error box with upper limit 11.5m on single (5 second) and 12.8m ( on coadd of 12 frames with total exposure 60 s) images. The message may be cited. [ DOI ]
