report on behalf of the MAXI team:

We examined MAXI/GSC all-sky X-ray images (2-20 keV)
after the LVC trigger S191110af at 2019-11-10 23:06:44.183 UTC (GCN 26222).

At the trigger time of S191110af, the high-voltage of MAXI/GSC was off,
and it was turned on at T0+768 sec (+12.8 min).
The first one-orbit (92 min) scan observation with GSC after the event
covered 70%
of the 90% credible region of the cWB skymap from 23:19:33 to 00:34:28
UTC (T0+769 to T0+5264 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.
