Status and Availability

ALTAIR with Natural Guide Star (NGS) or Laser Guide Star (LGS) is available with NIRI for imaging, subject to the limitations below, and with NIFS for IFU spectroscopy and coronography and with GNIRS for longslit spectroscopy.

LGS + P1 "super-seeing" mode is commissioned for NIRI and NIFS, which allows nearly full sky coverage for targets with elevations >40 degrees from Gemini North.  

The mode is currently limited for GNIRS spectroscopy use due to flexure issues.  See the LGS + P1 "Super Seeing" mode page for more information.
