The Portfolio Review Committee report ranked Gemini Observatory as a critical component of the U.S.'s future astronomical research resources and recommended that the U.S. retain a majority share in the international partnership for at least the next several years. However, given the constraints that were considered, the Committee recommended that the U.S. contribution to Gemini operations be capped in 2017 and beyond. NSF has since commissioned a National Research Council study, titled "A Strategy to Optimize the U.S. Optical/Infrared System in the Era of the Large Synoptic Survey Telescope". The report made a recommendation that NSF work with its partners in Gemini to ensure that Gemini-South is well positioned for faint-object spectroscopy early in the era of the Large Synoptic Survey Telescope (LSST). Observatory support for the development of a next-generation medium-resolution spectrograph over the next 5–6 years addresses this recommendation directly. With the signing of the new International Agreement in late 2015, support from the five signatories (the U.S., Canada, Argentina, Brazil, and Chile) is secured for the period 2016-2021. There is also a strong possibility that current limited-term partners, Australia and Korea, will continue their relationship with the observatory in this manner, or will seek to transition to being full participants before the end of the current agreement. The Gemini was one of the telescopes that observed the turn-on of a nuclear transient, along with the Swift space telescope (aka Neil Gehrels "Swift" Observatory since 2018) and the Hiltner telescope (MDM observatory). The transient event was called PS1-13cbe and was located in the Galaxy SDSS J222153.87+003054.2
