Abstract
ALTAIR, the Gemini North single conjugated Adaptive Optics system has been Gemini AO facility instrument since 2003. Used every single night for the Gemini primary mirror tunning, ALTAIR has been allocated for GEMini NIR instruments science programs including the Near Infrared Integral-field Spectrograph (NIFS), the Near Infrared Imager (NIRI) and the Gemini multi-function spectrograph (GNIRS). In this proceeding, we propose to review the actual performances of our 20 years old AO system. We will also describe the main instrument failure (Slow focus camera, Deformable mirror) that we had to fix to keep ALTAIR alive until the GNAO instrument venue (5 years from now).
