Mihara, (RIKEN),\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 S250201i at 2025-02-01 02:08:41.292 UTC.\n\nAt the trigger time of S250201i, the high-voltage of MAXI/GSC was off,\nand it was turned on at T0+844 sec (+14.1 min).\nThe first one-orbit (92 min) scan observation with GSC after the event covered 98%\nof the 90% credible region of the bayestar skymap from 03:09:42 to 03:22:16 UTC (T0+3661 to T0+4415 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.\n",
