Kondo (AGU)\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 S240422ed at 2024-04-22 21:35:13.417 UTC (GCN #36236).\n\nAt the trigger time of S240422ed, the high-voltage of MAXI/GSC was off,\nand it was turned on at T0+620 sec (+10.3 min).\nThe first one-orbit (92 min) scan observation with GSC after the event covered 100%\nof the 90% credible region of the bayestar skymap from 22:32:11 to 22:37:06 UTC (T0+3418 to T0+3713 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.
