We confirm this spectral type with near-infrared spectroscopy, which provides further evidence that 2MASS J11151597+1937266 is a low-surface gravity L dwarf. This object also shows significant excess mid-infrared flux, indicative of circumstellar material; and its strong H$\\alpha$ emission (EW$_{\\mathrm{H}\\alpha}=560\\pm82$ \\AA) is an indicator of enhanced magnetic activity or weak accretion.
