We observed the 70% credible region (~34 deg^2) of the localization map of
the BBH merger candidate, S190510g (LIGO/Virgo GCN 24950) with KMTNet
at Chile (CTIO) starting at 2019-07-02 09:03:19 UT. The images were taken in
R-band with 240 sec exposure time to the depth of R ~ 22 mag
(5-sigma detection). The central coordinate of each 2 deg x 2deg pointing is
given below. The search for transients is ongoing.
