GNIRS is now fully back in service on Gemini North. It is a heavily-subscribed instrument, accounting for 35% of allocated time in semester 2011A, and it is likely to remain popular when the final 2011B programs are approved. The first scientific publication from GNIRS on Gemini North is the discovery of a spectral type T8.5 (T = 600 to 650 K) brown dwarf in the Galactic plane by Ben Burningham (University of Hertfordshire, UK) and collaborators, available as a preprint or with summary information from Gemini at
