Gemini South Semester 2020A
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.
Scheduled classical runs are indicated by the last characters of the program ID, e.g., "C-1", whilst Priority Visitor programs are indicated with "PV".
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 and indicated in yellow and grey on the dates lines.  Dates above each month are color-coded to show weekends and holidays in red.
