We obtained three epochs of GMOS-N spectroscopy data of the likely companion to a unique new milli-second pulsar in a highly eccentric orbit. Pulsar timing provides an accurate mass for the companion star (1M) and its orbital period (95 days). Near-IR images detect a star at the pulsar position with colors consistent with a highly-reddened G star. If it can be shown that the G star is the only companion, then this system will provide new tests of General Relativity. Here, we present our preliminary results on the association of the possible companion star to the pulsar system.
