Abstract: On August 14, 2019 the LIGO/Virgo Collaboration (LVC) detected the gravitational waves spawned by a possible neutron star-black hole merger (NSBH), a rare event which was later designated as GW190814 by the LVC team. An extensive search for an optical counterpart --- a kilonova --- was undertaken by the Dark Energy Survey (DES) Gravitation Wave (GW) team using two instruments located in the Chilean Andes: the DECam imaging camera on the Blanco 4-m telescope and the Goodman spectrograph on the SOAR 4-m telescope. I will describe the LVC detection of GW190814 and the DES-GW team’s search for its optical counterpart, the results of the search, and the lessons learned for optical follow-up of future LVC gravitational wave detections.
