We report optical imaging follow-up observations for a part of
the equator region (RA:13h, Dec:0d) of S190510g (LIGO Scientific
Collaboration and the Virgo Collaboration, GCN #24442) with Hyper
Suprime-Cam (HSC) attached to the 8.2-m Subaru Telescope. HSC
has a circular field-of-view whose area is 1.7 deg^2.
We performed Y-band imaging observations on 2019-05-10 UT. The
exposure time per frame was 30 sec. We covered 140 deg^2 around
the high probability area in the equator region of the Bayestar skymap
of S190510g with 120 pointings of HSC. We revisited each pointing
position two times. The 5-sigma limiting AB magnitude of Y-band was
about 22.7 mag.
The observed regions are as follows:
