The Altair electronics remain in an unstable state and are not suitable for operations at this time. Investigations are continuing. We will not install NIFS until Altair is reliably functional. It is likely that NIFS will not be available until the later blocks scheduled in 2023B: in November and January.
The 2023B Gemini Observatory Call for Proposals has been released. Proposals are being accepted for observations from 1 August 2023 to 31 January 2024. Gemini North and Gemini South are expected to have 162 and 141 nights available for science, respectively. A new version of the Phase I Tool (PIT) has been released to support proposal submissions.
NIFS is temporarily unavailable at Gemini North. The cold head is being exchanged because the instrument was not holding temperature. We expect the instrument to be available again during the week of January 31.
NIFS has a cryogenic issue which started at the time of the earthquake and power outage on Monday 5th July. This problem has developed and it is now clear that the instrument must be warmed up completely to effect mitigation. NIFS will remain off the telescope until this is completed; NIRI will remain on for the time being.
NIFS has been available since semester 2006B for classical and queue scheduled observing at Gemini-North.
January 2013: On Instrument Wave Front Sensor (OIWFS) is unavailable due to a faulty sensor.
October 2012: New 'LGS+P1' guide mode is now operational, allowing 'seeing improver' AO correction with essentially 100% sky coverage.
