Gemini North Semester 2025A -- Dates are local HST
The semester calendar shows multi-instrument queue nights, 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).
GMOS-N will be out of operations Apr21 until ~May05.
“onsky” label noted in the GMOS schedule starting May 5 indicates the beginning of on-sky checks.
Science observations will resume progressively as we complete these checks, but this process may take several days.
