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 S190707q at 2019-07-07 09:33:26.181 UTC (GCN 25012).\n\nAt the trigger time of S190707q, the high-voltage of MAXI/GSC was on.\nThe instantaneous field of view of GSC at the GW trigger time covered 2% of the 90% credible region\nof the bayestar sky map, in which we found no significant new X-ray source.\nThe first one-orbit (92 min) scan observation with GSC after the event covered 93%\nof the 90% credible region of the bayestar skymap from 09:33:26 to 11:05:21 UTC (T0+0 to T0+5515 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.",
