behalf of a larger collaboration


We observed 120 host galaxy candidates in the 50% localization area of the BNS
merger candidate, S190425z, detected by LIGO/Virgo (GCN #24168) using the
KMTNet 1.6m telescopes at SSO, SAAO, and CTIO. The observation started at
2019-04-25 12:28 UT, and the images were taken in R-band with 120 sec
exposure time. No obvious transient has been identified. The list of
the targets
is given below.
