Gemini North Semester 2020A  - Dates are local HST
The semester calendar shows multi-instrument queue nights, scheduled classical or Priority Visitor runs, and engineering or commissioning. Dates are local HST, dates in red are weekends and holidays. 
Instruments potentially usable are indicated by the colored-horizontal bands (see color key below).
Note: Rapid ToO PIs should always check  the current configuration page.
Altair is curreuntly unavailable, i.e. no AO observations (LGS or NGS) and work is on going to fix it. Until then, Altair is shown as "white", i.e. unavailable for the whole semester.
NIFS will be put on the telescope after Altair has been repaired. Maroon-X is on the bottom port. We are uncertain when we can carry out the next instrument change.
