Abstract
We found an optical counterpart to the short GRB 170817A in our DECam observations performed the same night. Follow up FLAMINGOS2 spectroscopy through GS-2017B-Q-8 has provided an initial look at the source. This Gemini proposal will provide continued near-infrared imaging and spectroscopy of the source to maximize the return of the data in hand from our previous program. NIR data are the key to measuring the ejecta velocities and constraining the presence of r-process nucleosynthesis.
