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 S190630ag at 2019-06-30 18:52:05.179 UTC (GCN 24922).\n\nAt the trigger time of S190630ag, the high-voltage of MAXI/GSC was off,\nand it was turned on at T0+176 sec (+2.9 min).\nThe first one-orbit (92 min) scan observation with GSC after the event\ncovered 60%\nof the 90% credible region of the bayestar skymap from 18:58:20 to\n20:05:46 UTC (T0+375 to T0+4421 sec).\n\nNo significant new source was found in the region in the one-orbit\nscan 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.",
