We examined the MAXI/GSC all-sky X-ray images (2-20 keV) obtained
in the orbit and the day after the LVC trigger
G284239 at 2017-05-02 22:26:07.910 UTC (GCN 21060

).

MAXI/GSC scanned more than 88%
of the whole sky in the 92-min orbit, which includes 81.2% of the
90% regions in the LIB_skymap.
One day image covers 100% of the 90% regions
in the LIB_skymap.
No significant new source was found in these images.
The upper limits for the X-ray flux are different depending
on the part of the sky.
For instance, typical 2-20 keV 1-sigma (3-sigma) upper limits obtained
from the one-orbit and one-day images are
11(33) mCrab and  4(12) mCrab, respectively,
