TL;DR: In this paper, the Japanese collaboration for gravitational wave electro-magnetic (J-GEM) follow-up observations of SSS17a, an electromagnetic counterpart of GW170817, showed a 2.5mag decline in the z band during the period between 1.7 and 7.7 d after the merger.

TL;DR: The first detected gravitational wave from a neutron star merger was GW170817 as discussed by the authors, which showed a 2.5-mag decline in the $z-H$ band from 1.7 days to 7 days after the merger, which is not comparable with supernovae light curves at any epoch.
