In a recent search for unusually red L and T dwarfs, we identified 2MASS J11193254-1137466 as a likely young L7 dwarf and potential member of the TW Hydrae association. We confirmed its youth and membership using a Fast-Turnaround Gemini/Flamingos-2 R=600 spectrum, and a subsequent R=6,000 Magellan/FIRE spectrum. Being one of the brightest (Ks=14.75 mag) free-floating giant planet analogues, with a mass of 4.3-7.6 MJup, 2M 1119-1137 is one of the best possible targets for investigating exoplanetary atmospheres in detail. We propose to obtain an R=12,000 spectrum with GNIRS to measure a precise radial velocity and v sin(i) in a first step towards a full characterization of this giant planet analogue.
