System User Support (SUS)

System User Support (SUS) provides help to users for observing proposal preparation and submission to all of US O/IR System facilities that provide NSF-sponsored community access, including NOAO operated facilities. SUS also answers questions about post-observing data processing.

US observing time on the Gemini Observatory telescopes comprises the largest part of community open access to non-NOAO ground-based facilities.

SUS is part of the NOAO System Science Center (NSSC), and it includes the US National Gemini Office (US NGO). Information on the US NGO can be found at the new webpage

For further information, please contact the SUS/US NGO Head Letizia Stanghellini (
