(GCN #13430) and Gotz et al. (GCN #13434).\n\nFixing the source position to that of GRB 120711A,\nwe obtained the light curve corrected with the transit response\nwithin the GSC scan.\nIt was variable within the scan, and\nthe peak flux was  610 +- 130 (mCrab, 2-20 keV) on 2012-07-11 02:44:54 UT.",
