Kawakubo (LSU)\nreport on behalf of the MAXI team: \n\nWe examined MAXI/GSC all-sky X-ray images (2-20 keV)\nafter compact binary merger candidate S230802aq at 2023-08-02 11:33:59 UTC (GCN #34314).\n\nAt the trigger time of S230802aq, the high-voltage of MAXI/GSC was on.\nThe instantaneous field of view of GSC at the GW trigger time covered 1% 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 62%\nof the 90% credible region of the bayestar skymap from 11:33:59 to 13:05:58 UTC (T0+0 to T0+5519 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.
