The objects 2014 QO441 and 2014 QP441 were detected in data obtained during the 2013?14 and 2014?15 observing seasons by the Dark Energy Survey, using the Dark Energy Camera (DECam) on the 4-m Blanco telescope at Cerro Tololo Inter-American Observatory. Both are in high-inclination orbits (18fdg8 and 19fdg4, respectively). With an eccentricity of 0.104, 2014 QO441 has the most eccentric orbit of the 11 known stable Neptune Trojans. Here we describe the search procedure and investigate the objects' long-term dynamical stability and physical properties.
