(KASI), on behalf of a larger collaboration
We report the results from further KMTNet observation of the optical
counterpart candidates from DECam-GROWTH and DESGW (Andreoni et al. GCN
24467; Annis et al. GCN 24474; Sores-Santos et al. GCN 24480) of the BNS
merger candidate event, S190510g (LIGO/Virgo GCN 24448). This is a
follow-up report of the KMTNet result (Im et al. GCN 24493), adding data
points taken after our earlier report. With the additional data, we now
have at least one day cadence of KMTNet data of all the objects enabling us
to determine their variability for 1 day or more using internally
consistent photometry. The list of the observed targets are given below,
along with preliminary R-band magnitudes. None of the candidates below
show significant fading (> 0.5 mag) over ~1 day. All of the candidates show
very slow (<0.2 mag) or no fading, consistent with them being supernovae.
We thank the KMTNet staffs for performing the observation.
