Near-infrared (NIR)-wavelength observations of Uranus have been unable to locate any infrared aurorae, despite many attempts to do so since the 1990s. While at Jupiter and Saturn, NIR investigations have redefined our understanding of magnetosphere–ionosphere–thermosphere coupling, the lack of NIR auroral detection at Uranus means that we have lacked a window through which to study these processes at Uranus. Here we present NIR Uranian observations with the Keck II telescope taken on the 5 September 2006 and detect enhanced H3+emissions. Analysing temperatures and column densities, we identify an 88% increase in localized H3+column density, with no significant temperature increases, consistent with auroral activity generating increased ionization. By comparing these structures against the Q3mpmagnetic-field model and the Voyager 2 ultraviolet observations, we suggest that these regions make up sections of the northern aurora.
