Gemini South Semester 2024A
The semester calendar shows multi-instrument queue nights, priority visitor nights, scheduled classical runs and engineering or commissioning blocks.
Horizontal rows represent instrument ports, color-coded to indicate instruments mounted. Instruments are available for science unless otherwise noted.
Note: ToO PIs should always check the "what's available now" pages that are linked from the contents list for the most up-to-date information.
Engineering or commissioning blocks are shown across all rows when no backup queue is available (or telescope is closed).
New and full moon dates are shown on the left.  Dates above each month are color-coded to show weekends (orange) and holidays (green)
