Kawakubo (LSU) \nreport on behalf of the MAXI team: \n\nWe examined MAXI/GSC all-sky X-ray images (2-20 keV) \nafter the LVC trigger S190828l at 2019-08-28 06:55:09.886 UTC (GCN 25503). \n\nAt the trigger time of S190828l, the high-voltage of MAXI/GSC was off, \nand it was turned on at T0+387 sec (+6.5 min). \nThe first one-orbit (92 min) scan observation with GSC after the event covered 94% \nof the 90% credible region of the bayestar skymap from 07:01:46 to 08:10:26 UTC (T0+397 to T0+4517 sec).\n\nNo significant new source was found in the region in the one-orbit scan observation. \nA typical 1-sigma averaged upper limit obtained in one scan observation \nis 20 mCrab at 2-20 keV. \n\nIf you require information about X-ray flux by MAXI/GSC at specific coordinates, \nplease contact the submitter of this circular by email.",
