report on behalf of the MAXI team:

We examined MAXI/GSC all-sky X-ray images (2-20 keV)
after the LVC trigger S191105e at 2019-11-05 14:35:21.933 UTC (GCN 26182).

At the trigger time of S191105e, the high-voltage of MAXI/GSC was off,
and it was turned on at T0+1729 sec (+28.8 min).
The first one-orbit (92 min) scan observation with GSC after the event covered 72%
of the 90% credible region of the bayestar skymap from 15:04:11 to 15:20:01 UTC (T0+1730 to T0+2680 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.
