No credible transients have \nbeen found on our images. The 3 sigma unfiltered upper limit is 10.6.\nMASTER-II robotic telescope (MASTER-Net: http://observ.pereplet.ru) \nlocated in Kislovodsk was pointed to the GRB140105A 21 sec after notice \ntime and 45 sec after trigger time at 2014-01-05 01:33:46 UT.\n\nAfter pointing by FERMI alert we cover 90% of 1-sigma and 70% of 3-sigma \nFERMI-GBM error box.  We didn't find new object in error box on single and \ncoadd images. The 3 sigma upper limit on single 5 seconds exposure image \nis 10.6 and 12.0 on coadd of 24 images with total exposure 120 seconds.\nThe positions of all iPTF optical afterglow candidates (Singer et al., GCN \n15686) are covered by out cameras since 48 sec. after the trigger but \nthere are no flares up to 10.6 mag. on their place.\n\nThe movie is available here \nhttp://master.sai.msu.ru/static/GRB/GRB140105A/GRB140105A.gif\n\nThe map of error box and our FOV is available at \nhttp://master.sai.msu.ru/static/GRB/GRB140105A/GRB140105A_map.png\n\nThe pointing time informations in our previous telegram Gorbovskoy et al. \nGCN 15692 are not correct. We apologize for this inaccuracy.\n\n\n\nThe message may be cited.",
