report on behalf of the MAXI team:

We examined MAXI/GSC all-sky X-ray images (2-20 keV)
after compact binary merger candidate S241114bi at 2024-11-14 23:52:58.148 UTC (#38228).

At the trigger time of S241114bi, the high-voltage of MAXI/GSC was off,
and it was turned on at T0+792 sec (+13.2 min).
The first one-orbit (92 min) scan observation with GSC after the event covered 94%
of the 90% credible region of the bayestar skymap from 00:06:11 to 01:13:09 UTC (T0+793 to T0+4811 sec).

No significant new source was found in the region in the one-orbit scan observation.
A typical 1-sigma averaged upper limit obtained in one scan observation
is 20 mCrab at 2-20 keV.

If you require information about X-ray flux by MAXI/GSC at specific coordinates,
please contact the submitter of this circular by email.
